What are linear equations?

A linear equation is one that has the form Ax+By=C. This definition comes from mathematics. It consists of two variables combined with a constant value that exists in each of them.

The values of the variables will be obtained when the system of linear equations is solved; this is referred to as the solution of a linear equation.

Given the linear equation y = 2x + 4

If x = -4

y =2(-4) + 4

y = -4

If x = -2

y =2(-2) + 4

y = 0

If x = 0

y =2(0) + 4

y = 4

If x = 2

y =2(2) + 4

y = 8

Hence the complete table using the function is

It takes Evelyn, traveling at 36 mph, 20 minutes longer to go a certain distance than it takes Sarah traveling at 60 mph. Find the distance
traveled.

Answers

The distance travelled by both Evelyn and Sarah is 30 miles.

Given,

The speed travelled by Evelyn = 30 mph

Time taken by Evelyn to cover a distance = 20 minutes

Speed travelled by Sarah = 60 mph

We have to find the distance travelled by both of them.

Speed = distance / time

Then,

Distance = speed x time

Lets take x as the distance.

Then,

36 × (x + 20) = 60x

36x + 720 = 60x

60x - 36x = 720

24x = 720

x = 720/24

x = 30

That is,

The distance travelled by both Evelyn and Sarah is 30 miles.

(b) P(x < 4) = 0.29

(c) P(x= 6) = 0.17

(d) P(x ≥ 5) = 0.34

STEP-BY-STEP EXPLANATION:

The probability in each case would be the specific amount divided by the total amount, therefore, we calculate the total amount and the probability in each case, like this:

[tex]\begin{gathered} 5+10+2+9+33+12+15+3+1\:=\:90 \\ \\ P(0)=\frac{5}{90}=0.06 \\ \\ P(1)=\frac{10}{90}=0.11 \\ \\ P(2)=\frac{2}{90}=0.02 \\ \\ P(3)=\frac{9}{90}=0.1 \\ \\ P(4)=\frac{33}{90}=0.37 \\ \\ P(5)=\frac{12}{90}=0.13 \\ \\ P(6)=\frac{15}{90}=0.17 \\ \\ P(7)=\frac{3}{90}=0.03 \\ \\ P(8)=\frac{1}{90}=0.01 \end{gathered}[/tex]

Therefore, the table would look like this:

24. A rocket is launched into the air. Its height in feet, after x seconds, is given by the equation The starting height of the rocket is h(x)=-16x’ +300x + 20 The maximum height is The rocket hits the ground after seconds.

Answers

Well we just need to do the analise of the function h, so for the first question we need to know what is the value of h when x=0, so if we evaluate we see that

[tex]h(0)=-16(0)^2+300(0)^{}+20^{}=20^{}[/tex]

So the first answer is that the start heigth of the rocket is 20.

Now for the second we need to do the derivate and see the critical ponit to know the maximum, we are going to calculate first the derivate, so

[tex]h^{\prime}(x)=-32x^{}+300[/tex]

now we need to find the critical ponits so for this, we are going to see when h'(x) = 0, this meand when the derivate is equal to zero, so h'(x) = 0 when

[tex]\begin{gathered} -32x\text{ + 300 =0} \\ 300\text{ = 32x} \\ \frac{300}{32}=x \end{gathered}[/tex]

to see if this critical poni is a maximum we need to calculate the secon derivate and see that the second derivate valued in 300/32 is smaller than 0, so

[tex]h^{\doubleprime}(x)\text{ = -32}[/tex]

now when x= 300/32 we have that h''(x) is -32 because the second derivate is constant, in this case h''(300/32) < 0, because of this the answer is that 300/32 is the maximum, bur 300/32 = 75/8.

Now for the third question, we need to see the roots of h, so we need to see when h is zero, so for wich values of x we have that h(x) = 0, then

[tex]-16x^2+300x+20=0^{}[/tex]

we can solve this with the quadratic equation to solve this kind of equations. This equation is

the answer is x = (-300 - v/ 91280)/(-32) or x = (-300 + v/ 91280)/(-32) and this is equal to x = (300 + v/ 91280)/(32) or x = (300 - v/ 91280)/(32) if you prefer. We can also write the answer in a simpler way: x = (75 + v/ 5705)/(8) or x = (75 - v/ 5705)/(8), this is

A contractor bought 10.8 ft² of sheet metal. He has used 3.5 ft² so far and has $219 worth of sheetmetal remaining. The equation 10.8x - 3.5x = 219 represents how much sheet metal is remainingand the cost of the remaining amount. How much does sheet metal cost per square foot?

Answers

[tex]10.8x-3.5x=219[/tex]

The first step to do is to combine 10.8x - 3.5x and that is equal to 7.3x.

[tex]7.3x=219[/tex]

The next step is to divide both sides by 7.3 to solve for x.

[tex]\begin{gathered} \frac{7.3x}{7.3}=\frac{219}{7.3} \\ x=30 \end{gathered}[/tex]

Therefore, the remaining sheet metal is 7.3 ft² and the cost per square foot of sheet metal is $30.

Calculating a rate of change

What is the vertical change form Point A to Point B?


What is the horizontal change from Point A to Point B ?


What is the rate of change shown on the graph? Give the answer as a decimal rounded to the nearest tenth, if necessary?

Answers

Hello there. To solve this question, we'll have to remember some properties about rate of change.

Given the points A and B from a line, we want to determine the vertical change and the horizontal change between the points and then, using these values, determine the rate of change of the function (the line passing through them).

For this, we first find the coordinates of the points.

[tex]A=(2,1)\text{ and }B=(4,2)[/tex]

The vertical change is the difference between the y-coordinates of the points, hence

[tex]y(B)-y(A)=2-1=1[/tex]

The horizontal change is given by the difference between the x-coordinates of the points, therefore

[tex]x(B)-x(A)=4-2=2[/tex]

The rate of change of this function is, finally, given by the ratio between the vertical (rise) and horizontal (run) changes of the function:

[tex]\dfrac{1}{2}=0.5[/tex]

This is the rate of change of this function.

We will have the following:

We will be able to tel apart sequences as follows:

Linear sequence: We have that linear sequences follow the form:

[tex]y=mx+b[/tex]

Here "x" represents the iteration value for the sequence, "m" the ratio (slope) and "b" a value that modifies the "position" of the sequence. This sequences grows in a linear manner.

Example:

[tex]\begin{cases}y_{}=2x+2 \\ \\ y_1=4 \\ y_2=6 \\ y_3=8 \\ \ldots\end{cases}[/tex]

Exponential sequence: We have that exponential sequences follow the form:

[tex]y=a_1(r)^{x-1}[/tex]

Here "a1" is the first term of the sequence, "r" is the ratio and "x" the iteration of the sequence.

We obtain the ratio as follows:

[tex]r=\frac{y_n}{y_{n-1}}[/tex]

Example:

[tex]\begin{cases}y=1(5)^{x-1}_{} \\ \\ y_1=1 \\ y_2=5 \\ y_3=25 \\ \\ \ldots\end{cases}[/tex]

The ratio for this case:

[tex]r=\frac{y_3}{y_2}\Rightarrow r=\frac{25}{5}\Rightarrow r=5[/tex]

Quadratic sequence: A quadratic sequence follows the general form

Answers

5 to 6 odds means that, out of 11 possible outcomes, odds are that there will be 5 of one kind of outcome and 6 of another kind of outcome.

In this case, you are given 5 to 6 odds, which means that out of 11 possible outcomes you will win a bet 5 times, and lose it 6.

In fraction, it will look like this:

State the domain using an appropriate notation and evaluate f(2)

Answers

Answer:[tex]\begin{gathered} \text{Domain=}\mleft\lbrace-7,0,2,8\mright\rbrace \\ f(2)=5 \end{gathered}[/tex]

Explanations:

The domain of a function or coordinates of a function are the input values of the function "x" for which the function exists.

For instance, given the coordinates of the function {(-7, 2), (0, -2), (2, 5), (8, 1)}, the corresponding value of the x-coordinates are the domain. Therefore the domain of the given coordinate points are given as;

[tex]\text{Domain}=\mleft\lbrace-7,0,2,8\mright\rbrace[/tex]

Get the value of f(2).

To get the value of f(2), we will find the y-value of the coordinate with a domain of 2. From the given coordinates, we can see that the coordinate that has a domain of 2 is (2, 5) and the corresponding y-value of the coordinate is 5. Hence f(2) = 5

d = 2q .........................................................................(1)

0.1d + 0.25q = 4.20 ................................................(2)

Explanation:

Let d be the number of dimes, and q be the number of quarters Sophie has.

Since she has twice as many quarters as dimes, and they are worth $4.20, we have:

d = 2q .........................................................................(1)

Also, because:

1 dime = $0.1

1 quarter = $0.25

0.1d + 0.25q = 4.20 ..................................................(2)

Equation (1) and (2) can be solved to determine the number of dimes and quarters

what is the area of the regular 15-gon with radius 12mm?

Answers

The regular pentagon can divide into 5 congruent isosceles triangles

The equal sides of each triangle have length r and vertex angle of measure 72 degrees

Then we will use the sine rule of the area to find the area of each triangle, then multiply it by 5 to get the area of the pentagon

Since the radius is 7mm, then

r = 7

[tex]A=5\times\frac{1}{2}\times r\times r\times sin72[/tex]

Substitute r by 7

[tex]\begin{gathered} A=5\times\frac{1}{2}\times7\times7\times sin72 \\ \\ A=116.5044232\text{ mm}^2 \end{gathered}[/tex]

Round it to the nearest whole number

A = 117 mm^2

The area of the pentagon is 117 mm^2

what is the rate change of the equation?Y=8x+20Remember Y=MX+B

Answers

The general equation of the line : y = m * x + b

where m is the slope , b is y -intercept

Given the function :

[tex]y=8x+20[/tex]

The rate of change of the equation = the slope of the function

So, by comparing the given equation to the general from

The slope = m = 8

So, the rate of change = 8

what are the lenghths of the legs in the triangle?give your answer in simplest radical form or rounded to the nearest hundredth.

Answers

Here, we are given a 45°-45°-90° triangle.

Let's find the length of the legs.

A 45°-45°-90° triangle is an isosceles triangle, and the two legs of an isosceles triangle are of equal lengths.

To find the length of each leg apply the formula:

[tex]c=a\sqrt[]{2}[/tex]

Where;

c = 12

Thus, we have:

[tex]12=a\sqrt[]{2}[/tex]

Solve for a:

Divide both sides by √2

[tex]\begin{gathered} \frac{12}{\sqrt[]{2}}=\frac{a\sqrt[]{2}}{\sqrt[]{2}} \\ \\ \frac{12}{\sqrt[]{2}}=a \\ \\ a=\frac{12}{\sqrt[]{2}} \\ \\ \text{Simplify the denominator:} \\ a=\frac{12}{\sqrt[]{2}}\ast\frac{\sqrt[]{2}}{\sqrt[]{2}} \\ \\ a=\frac{12\sqrt[]{2}}{2} \\ \\ a=6\sqrt[]{2} \end{gathered}[/tex]

Therefore, the length of each leg in radical form is 6√2

ANSWER:

[tex]6\text{ }\sqrt[]{2}[/tex]
