5x-4y=3(x+3) slope and y+x intercept

Answers

Answer 1

Answer:

Step-by-step explanation:

To find the slope of the line represented by the equation 5x-4y=3(x+3), we can rearrange the equation into slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

5x - 4y = 3(x + 3)

5x - 4y = 3x + 9

5x - 3x = 4y + 9

2x = 4y + 9

y = (2/4)x - 9/4

So, the slope of the line is 2/4, which can be simplified to 1/2.

To find the y-intercept, we can set x = 0 in the equation:

y = (1/2)(0) - 9/4

y = -9/4

Therefore, the y-intercept is -9/4.

To find the x-intercept, we can set y = 0 in the equation:

0 = (1/2)x - 9/4

9/4 = (1/2)x

x = (9/4) / (1/2)

x = 9/2

Therefore, the x-intercept is 9/2.

Answer 2

Answer:

Slope: -1/2 Y-Intercept: -9/4

Step-by-step explanation:

5x - 4y = 3x + 9

Subtract 3x from both sides

2x - 4y = 9

Divide both sides by -4

y = (-1/2)x + (-9/4)

a denominator of 4.

Answers

Answer:

The multiplication equation that shows how the denominators of 3/4 and 5/6 are related is:4 × 6 = 24To write an equivalent fraction with a denominator of 4, we need to find a number that, when multiplied by 4, gives us 24. That number is 6. So, we can multiply both the numerator and denominator of 3/4 by 6 to get:(3/4) × (6/6) = 18/2418/24 is equivalent to 3/4, but it has a denominator of 24 instead of 4. We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF), which is 6.(18/6) ÷ (24/6) = 3/4Therefore, the equivalent fraction of 3/4 with a denominator of 4 is 3/4 × 6/6 = 18/24, which simplifies to 3/4.

You need a 35% alcohol solution. On hand, you have a 245 mL of a 10% alcohol mixture. You also have 70% alcohol mixture. How much of the 70% mixture will you need to add to obtain the desired solution?

You will need mL of the 70% solution
to obtain mL of the desired 35% solution.

Answers

Using percentage, we can get that 7ml of the 70% solution will be needed.

What do you mean by percentage?

A percentage's denominator, often referred to as a ratio's or a fraction's, is always 100. Sam, for instance, would have gotten 30 out of a potential 100 points if his math test score had been 30%. It is written as 30:100 in ratio form and 30/100 in fraction form.

In this context, "%" is read as "percent" or "percentage" to represent a percentage. By "division by 100," the percent symbol can always be changed to a fraction or decimal equivalent.

In the given question we get the equation,

35(245) + 0.75x = 0.4(245+x) = 98 + 0.4x

85.75 + 0.75x = 98 + 0.4x

0.35x = 98-85.75 = 12.25

x = 12.25/.35 = 35 mL of 75% solution

mixed with 245 mL of 35% it yields 280 mL of 40% so,

35 is within 5 of 40

Find the equation for the ellipse

Answers

Using the data points given, the equation is [tex]\frac{\Big(\frac{(x - 4)^2}{25}+ (y + 2)^2\Big)}{25} = 1[/tex].

What is an ellipse?

An ellipse is a locus of a point that moves in such a way that its perpendicular distance from a fixed straight line (directrix) and its distance from a set point (focus) remain constant. which is smaller than unity, i.e. eccentricity(e).

We are given that the center of the ellipse is at (4,-2), and a vertex is at (9,-2).

We know that the distance from the center to a vertex is a, where a is the length of the semi-major axis.

Therefore, we have -

a = 9 - 4 = 5

Since the point (4,3) is on the ellipse, we can use the distance formula to find the length of the semi-minor axis -

c = distance from (4,-2) to (4,3)

c = [tex]\sqrt{((4-4)^2 + (3-(-2))^2}[/tex]

c = 5

Now, we can use the equation of an ellipse -

[tex]\frac{\Big(\frac{(x - h)^2}{a^2}+ (y - k)^2\Big)}{b^2} = 1[/tex]

where (h,k) is the center of the ellipse, a is the length of the semi-major axis, and b is the length of the semi-minor axis.

Plugging in the values we have found, we get -

[tex]\frac{\Big(\frac{(x - 4)^2}{25}+ (y + 2)^2\Big)}{25} = 1[/tex]

Therefore, the equation for the ellipse is [tex]\frac{\Big(\frac{(x - 4)^2}{25}+ (y + 2)^2\Big)}{25} = 1[/tex].

Answers

Answer: a. To shift the graph downwards 5 units, we subtract 5 from the function, to shift it left 3 units, we add 3 to the input (the x-value), to stretch the graph vertically by a factor of 4, we multiply the function by 4, and to reflect it about the x-axis, we multiply the entire function by -1. Thus, the new function is:

g(x) = -4(1/2)^(x+3) - 5

b. To find the y-intercept, we set x=0 in the equation and solve for y:

g(0) = -4(1/2)^(0+3) - 5 = -9

Thus, the y-intercept is (0, -9).

c. The domain of the function g(x) is all real numbers, since there are no restrictions on the input x.

d. The range of the function g(x) is (-∞, -5], since the function is shifted downwards 5 units and stretched vertically by a factor of 4, which means that the maximum value of the function is -5, and it can take any value less than or equal to -5.

Answers

Answer: Since there are 500 tumblers in each batch, there are a total of:

500 tumblers/batch × 3 batches = 1500 tumblers

To make a set of 3 tumblers with one tumbler of each color, we can choose one tumbler from each batch. There are 500 choices for the tumbler from the red batch, 500 choices for the tumbler from the yellow batch, and 500 choices for the tumbler from the purple batch. Therefore, there are:

500 choices for the first tumbler × 500 choices for the second tumbler × 500 choices for the third tumbler = 500^3 = 125,000,000 possible sets of 3 tumblers.

However, we are interested in the number of sets that can be made from the available tumblers. Each set requires one tumbler from each batch, and since there are 500 tumblers in each batch, we can make:

500 sets/batch = 500 sets/batch × 3 batches = 1500 sets

Therefore, we can make a total of 1500 sets of 3 tumblers from the available tumblers.

Total Surface Area:

Answers

The total surface area of the rectangular prism is 94 cm2.

What is surface area?

Surface area is the measurement of the total area of a three-dimensional object. It is the sum of all the areas of the faces or surfaces of a 3D shape.

The total surface area of a 3D object is the sum of the areas of all its faces. The formula to calculate the total surface area of a 3D object is:

Total Surface Area = 2(Length x Width) + 2(Length x Height) + 2(Width x Height)

Where Length, Width, and Height are the dimensions of the 3D object.

For example, if you have a rectangular prism with Length = 5 cm, Width = 4 cm, Height = 3 cm, then the total surface area is:

Total Surface Area = 2(5 cm x 4 cm) + 2(5 cm x 3 cm) + 2(4 cm x 3 cm)

 = 40 cm2 + 30 cm2 + 24 cm2

 = 94 cm2

Therefore, the total surface area of the rectangular prism is 94 cm2.

In conclusion, the formula to calculate the total surface area of a 3D object is: Total Surface Area = 2(Length x Width) + 2(Length x Height) + 2(Width x Height). Examples can be used to better understand the concept and apply the formula to solve for the total surface area.

Mathematicians examine numbers with their modifications, equations and associated structures, forms and their locations, and feasible positions for these things. The term "function" indicates the connection between a collection of inputs, each of which has a corresponding output. A function is a connection of inputs and outputs where each supply leads to a specific, identifiable outcome. Each function is assigned a domain, a codomain, or a scope. The letter f is widely used to denote functions (x). The symbol for entry is an x. The four primary types of accessible capabilities are on functions, yet another skills, so multiple capabilities, in capabilities, and on operations.

The function f(x) = -6t(t-5) reflects the football's height at time t. When the football lands, its height will be zero.

To determine the time the ball is in the air, we must first determine when f(t) = 0. As a result, we may set the equation to zero and solve for t:

-6t(t-5) = 0

This equation is valid for t = 0 or t = 5. When the ball is tossed, time t = 0 occurs, and time t = 5 occurs when the ball strikes the ground. The time the ball is in the air is calculated as follows: time in air = t final - t initial = 5 - 0 = 5 seconds.

An equation is a mathematical statement that indicates the equality of two expressions. It is made up of one or more variables, constants, and mathematical operations. An equation consists of two sides, left-hand side (LHS) and right-hand side (RHS), separated by an equal sign (=).

The purpose of an equation is to find the value(s) of the variable(s) that satisfy the given conditions. To solve an equation, we need to isolate the variable on one side of the equation and simplify the other side of the equation until we obtain a solution or solutions.

The equation shows that the amount of money Anju earns is directly proportional to the number of chores she does. Each chore is worth $3, so if Anju does c chores, she earns 3c dollars.

For example, if Anju does 5 chores, she can use the equation to find how much money she earned:

this is the standard form of the hyperbola that the receiver sits on if the transmitters behave as foci of the hyperbola.

What is hyperbola ?

A hyperbola is a type of conic section that has two separate parts, called branches, which are mirror images of each other. It is defined as the set of all points in a plane, such that the difference between the distances from two fixed points, called foci, is a constant. Hyperbolas have many applications in science, engineering, and mathematics.

Given two LORAN transmitters located at the coordinates [tex]$(x_1, y_1)$[/tex] and [tex](x_2, y_2)$[/tex], where unit distance on the coordinate plane is measured in miles.

Let the coordinates of the receiver be [tex](x,y)$.[/tex]

The distance from the receiver to the first transmitter is given by [tex]$\sqrt{(x - x_1)^2 + (y - y_1)^2}$[/tex], and the distance from the receiver to the second transmitter is given by [tex]\sqrt{(x - x_2)^2 + (y - y_2)^2}$.[/tex]

Since the difference in the distances from the receiver to these transmitters is 180 miles, we have:

[tex]$$\sqrt{(x - x_1)^2 + (y - y_1)^2} - \sqrt{(x - x_2)^2 + (y - y_2)^2} = 180$$[/tex]

Squaring both sides, we get:

[tex]$$(x - x_1)^2 + (y - y_1)^2 - 2\sqrt{(x - x_1)^2 + (y - y_1)^2} \sqrt{(x - x_2)^2 + (y - y_2)^2} + (x - x_2)^2 + (y - y_2)^2 = 180^2$$[/tex]

Rearranging, we get:

[tex]$$(x - x_1)^2 + (y - y_1)^2 - (x - x_2)^2 - (y - y_2)^2 = 4\sqrt{(x - x_1)^2 + (y - y_1)^2} \sqrt{(x - x_2)^2 + (y - y_2)^2} - 180^2$$[/tex]

Using the identity $a^2 - b^2 = (a + b)(a - b)$, we can simplify the left-hand side as:

[tex]$$4x(x_2 - x_1) + 4y(y_2 - y_1) = 4\sqrt{(x - x_1)^2 + (y - y_1)^2} \sqrt{(x - x_2)^2 + (y - y_2)^2} - 180^2$$[/tex]

Squaring both sides again and simplifying, we get:

[tex]$$16[(x_2 - x_1)^2 + (y_2 - y_1)^2]x^2 - 32(x_2 - x_1)x^3 + 16(x_2 - x_1)[(y_2 - y_1)^2 + (x_2 - x_1)^2 - 180^2]x + 16[(y_2 - y_1)^2 + (x_2 - x_1)^2]y^2 - 32(y_2 - y_1)y^3 + 16(y_2 - y_1)[(y_2 - y_1)^2 + (x_2 - x_1)^2 - 180^2]y + [(x_2 - x_1)^2 + (y_2 - y_1)^2 - 180^2]^2 = 0$$[/tex]

this is the standard form of the hyperbola that the receiver sits on if the transmitters behave as foci of the hyperbola.

Therefore, [tex]$$16[(x_2 - x_1)^2 + (y_2 - y_1)^2]x^2 - 32(x_2 - x_1)x^3 + 16(x_2 - x_1)[(y_2 - y_1)^2 + (x_2 - x_1)^2 - 180^2]x + 16[(y_2 - y_1)^2 + (x_2 - x_1)^2]y^2 - 32(y_2 - y_1)y^3 + 16(y_2 - y_1)[(y_2 - y_1)^2 + (x_2 - x_1)^2 - 180^2]y + [(x_2 - x_1)^2 + (y_2 - y_1)^2 - 180^2]^2 = 0$$[/tex]

this is the standard form of the hyperbola that the receiver sits on if the transmitters behave as foci of the hyperbola.

Consider the following function.

h(x)=(x−4)2−1
Step 2 of 4 : Find the x-intercepts, if any. Express the intercept(s) as ordered pair(s).

Answers

To find the x-intercepts of the function h(x) = (x - 4)^2 - 1, we need to set h(x) equal to zero and solve for x:

0 = (x - 4)^2 - 1

Adding 1 to both sides, we get:

1 = (x - 4)^2

Taking the square root of both sides, we get:

±1 = x - 4

Adding 4 to both sides, we get:

x = 4 ± 1

Therefore, the x-intercepts of the function h(x) are (3, 0) and (5, 0).

Each of the following functions f,g,h, and h represents the amount of money in a bank account in dollars as a function of time x, in years they are each written in form m(x)= a•b

Answers

Answer:

f(x)  :  exponential growth

g(x);  exponential growth

h(x):  exponential growth

j(x):   exponential decay

Step-by-step explanation:

In an exponential function such as
[tex]m(x) = a \cdot b^x[/tex]

the factor that determines whether it is a growth or decay function depends entirely on the value of b since x cannot be negative

If b > 1, it is a growth function

If b < 1 then it is a decay function

If b = 1 neither growth or decay function values are constant

In this context
f(x) has b = 2 > 1 . Hence it is a growth function
g(x) has b = 3 > 1 hence growth function
h(x) has be = 3/2 > 1; hence growth function
j(x) has be = 0.5 < 1 hence decay function

Answer:

O f(x)  :  exponential growth

O g(x);  exponential growth

O h(x):  exponential growth

O j(x):   exponential decay

Step-by-step explanation: I used to do this before :)
