Suppose a line, with a slope of -3 and a y-intercept of 4, is translated -4 units along the x-axis and 6 units along the y-axis. What is the equation of this new line?
Answers
Answer:
[tex]y=-3x-2[/tex]
Step-by-step explanation:
Slope-intercept form of a linear equation: [tex]y=mx+b[/tex]
where:
[tex]m[/tex] is the slope[tex]b[/tex] is the y-interceptGiven:
slope (m) = -3y-intercept (b) = 4Equation of line: [tex]y=-3x+4[/tex]
If the line is translated -4 units along the axis, we need to substitute
[tex]x \rightarrow (x+4)[/tex]
If the line is translated 6 units along the y-axis, we need to add 6 to the equation:
[tex]\implies y=-3(x+4)+4+6[/tex]
[tex]\implies y=-3(x+4)+10[/tex]
[tex]\implies y=-3x-12+10[/tex]
[tex]\implies y=-3x-2[/tex]
Answer:
y = -3x - 2
Step-by-step explanation:
Rules to remember :
f(x + a) = translated 'a' units leftf(x - a) = translated 'a' units rightStandard form of the original equation
y = mx + bhere m = slope and b = y-intercept⇒ y = -3x + 4Translating -4 units along the x-axis
y = -3(x + 4) + 4y = -3x - 12 + 4y = -3x - 8Translating 6 units along the y-axis
y = -3x - 8 + 6y = -3x - 2Paul is making grey paint. He mixes black and white paint in the ratio 1:3. He makes 35 litres of grey paint. How much white paint does he use?

Answers
The table of values of function g(x) and the function f(x) = 5x3 + 2x2 – 6x + 7 are illustrations of exponential functions and polynomial functions
2. The type of function g(x)The values on the table can be represented as:
(x, g(x)) = (-3, 0.375) (-1, 0.75) (1, 1.5) (3, 3) (5, 6) (7,12) (9, 24)
The above values show that as the values of x increases by 2, the values of function g(x) doubles.
Only an exponential function has this property.
Hence, the table of values represents an (a) exponential function.
3. Example of a polynomial functionA polynomial function is represented as:
y = ax^n + bx^n-2 + .......... + d
Using the above format, the function that is a polynomial function is (a) f(x) = 5x3 + 2x2 – 6x + 7
4. Key features in the functionsThe functions are given as
f(x) = 2x2 + 7x + 6
g(x) = 2x + 5
Set x to 0 to calculate the y-intercept
f(0) = 2(0)2 + 7(0) + 6 = 6
g(x) = 2^0 + 5 = 6
Hence, both functions have the same (c) y-intercept

A pet store has 4 tanks of fish. Each tank has 32 fish. How many fish does the store have?
Answers
Answer:
128
Step-by-step explanation:
32 × 4 = 128
Each tank has 32, and there are four, so 32 times 4.
The store has 128 fish in the tank.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that pet store has 4 tanks of fish. Each tank has 32 fish.
Therefore,
Total fish = Number of fish that a tank can hold x Number of tanks
32 × 4 = 128
Hence, we get 32 for each tank, and there are four,
Thus, 32 times 4.

The sum of two consecutive odd numbers is 24. Find the numbers.
Answers
Answer:
numbers = 11, 13
Explanation:
Let the two consecutive odd numbers be: n and n + 2
==========
n + n + 2 = 242(n) + 2 = 242(n) = 24 - 22(n) = 22n = 11⇒ One number: 11
⇒ Another number: 11 + 2 = 13
The sum of two consecutive odd numbers is 24. Find the numbers .
Given : -Sum of two consecutive odd no. = 24To Find : -We have to find the numbers .
Concept : -In this question we have to find the numbers by assuming the numbers and forming equations to finally get the appropriate answer .
To Assume : -Let first odd no. be x .Let second odd no. be x + 2So let's get started by solving : -[tex] \longrightarrow \: x + 2 + x= 24[/tex]
Now adding them ,
[tex] \longrightarrow \: 2x + 2 = 24[/tex]
Now taking 2 common ,
[tex] \longrightarrow \: 2(x + 1) = 24[/tex]
Now dividing 24 by 2 ,
[tex] \longrightarrow \: x + 1 = \frac{24}{2} [/tex]
We get ,
[tex] \longrightarrow \: x + 1 = 12[/tex]
Now transposing 1 to right hand side ,
[tex] \longrightarrow \: x = 12 - 1[/tex]
So ,
[tex] \longrightarrow \: \boxed{\bold{ x = 11}}[/tex]
Therefore value of first number is 11 .
Now , other consecutive no. be x + 2 . So
11 + 213Therefore value of second number is 13 .
Verifying :According to question sum of two consecutive no. is 24. So :

The following table represents the production cost g(x), in dollars, for x number of units produced by company 2:
Answers
The function of the production cost is a quadratic function, and the maximum production cost of the company is $340
How to determine the maximum production cost of the company?The function of the production cost is given as:
f(x) = 0.15x² - 6x + 400
Differentiate the function
f'(x) = 0.3x - 6
Set the function to 0
0.3x - 6 = 0
Add 6 to both sides
0.3x = 6
Divide both sides by 0.3
x = 20
Substitute x = 20 in f(x) = 0.15x² - 6x + 400
f(20) = 0.15 * 20² - 6 *20 + 400
Evaluate
f(20) = 340
Hence, the maximum production cost of the company is $340

Solve for x and y
7y - 5x = 45
x = 8 – 2y
Answers
Answer:
Hope the pictures will help you.
The solution to the system of equations is x = -2 and y = 5.
What is the solution to the system of equations?Given the parameters:
7y - 5x = 45
x = 8 - 2y
To solve the system of equations, substitute the expression for x from the second equation into the first equation.
7y - 5x = 45
Plug in x = 8 - 2y:
7y - 5( 8 - 2y) = 45
7y - 40 + 10y = 45
Collect and add like terms:
7y + 10y = 45 + 40
17y = 85
y = 85/17
y = 5
Plug the value of y into the second equation and solve for x:
x = 8 - 2y
Plug in y = 5:
x = 8 - 2( 5 )
x = 8 - 10
x = -2
Therefore, the value of x is -2 and y is 5.

Answers
The scientific value for n that will make the equation (4.8 × 10^(-3))(n) = 9.6 × 10^9 true is given by: Option D: 2.0 × 10^(12)
How does scientific notations work?The number is written in the form [tex]a \times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
Better readability due to compact representation
Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.
Finding the value of n from the given equation:
[tex](4.5 \times 10^{-3}) \times n = 9.6 \times 10^9\\\\\text{Dividing both the sides by } (4.5 \times 10^{-3}) \\\\n = \dfrac{9.6 \times 10^9}{4.5 \times 10^{-3}} = \dfrac{9.6}{4.5} \times \dfrac{10^{9}}{10^{-3}}\\\\n \approx 2.1333 \times 10^{9-(-3)} = 2.1333 \times 10^{12} \approx 2.0 \times 10^{12}[/tex]
Thus, the scientific value for n that will make the equation (4.8 × 10–3)(n) = 9.6 × 10^9 true is given by: Option D: [tex]2.0 \times 10^{12}[/tex]

Using correlation coefficients, it is found that the value of r is greater than 0 and close to 1, as the scatter-plot is increasing linearly.
What is a correlation coefficient?It is an index that measures correlation between two variables, assuming values between -1 and 1.If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.Researching the problem on the internet, it is found that the relation is modeled by an increasing scatter-plot, hence r > 0. There are very few points in which there are oscillations, which indicate a strong relationship, hence r is closer to 1.

Similarities
They both follow strict laws (typically stricter for math).
Practice makes perfect: both can be learned to points of practical perfection.
The brain must first attribute meaning or value to elements of either in order to build a learning pattern.
Differences:
Math is learned under assumptions of perfection (2 + 2 = 4 ALWAYS); whereas, language is learned under assumptions of reality (2 + 2 may be 5 for significantly larger values of 2). In other words, 2 average sized men plus 2 average sized Texans would more likely equal 5 or more average sized men.
Math is logical and language is largely artistic.
