The given equation is

[tex]y=\frac{4}{3}x-7[/tex]The slope of the given line is 4/3 because it's the coefficient of *x*.

Now, the new line has a slope of 4/3 too because parallel lines have equal slopes.

We know that the new line passes through the point (5, -8). Let's use the point-slope formula to find the equation.

[tex]y-y_1=m(x-x_1)[/tex]Replacing the points and the slope, we have.

[tex]\begin{gathered} y-(-8)=\frac{4}{3}(x-5) \\ y+8=\frac{4}{3}x-\frac{20}{3} \\ y=\frac{4}{3}x-\frac{20}{3}-8 \\ y=\frac{4}{3}x+\frac{-20-24}{3} \\ y=\frac{4}{3}x-\frac{44}{3} \end{gathered}[/tex]Therefore, the equation of the new line is y = (4/3)x - (44/3).00:00 Jayden evaluated the expression a = (2 + 1.5) for a = 14. He said that the answer was 8.5. Choose True or False for each statement Choose... Jayden's solution is incorrect. Choose... Jayden added in the parentheses before dividing. Choose... Jayden substituted the wrong value for a. Choose... Jayden divided 14 by 2 and added 1.5.

**Explanation:**

Let's see what's the value of the expression if we substitute a = 14:

[tex]14\colon(2+1.5)=14\colon3.5=4[/tex]So definetly Jayden's solution is not correct.

Let's check the second statement: that's what we just did - add the parentheses before dividing. If Jayden would've done that he would have arrieved at the same solution we did, so definetly this statement is false

The third statement could be true. Let's see which value of a gives 8.5 as a result:

[tex]\begin{gathered} a\colon(2+1.5)=8.5 \\ a\colon3.5=8.5 \\ a=8.5\times3.5 \\ a=29.75 \end{gathered}[/tex]If 'a' were 29.75, Jayden would be correct.

Let's see what happens if we divide 14 by 2 and then add 1.5:

[tex](14\colon2)+1.5=7+1.5=8.5[/tex]This is the result Jayden got, so definetly this is one option for what he did wrong.

**Answer:**

• Jayden's solution is incorrect: ,true

,• Jayden added in the parentheses before dividing:, ,false

,• Jayden substituted the wrong value for a: ,true

,• Jayden divided 14 by 2 and then added 1.5: ,true

A 56-inch **board **is to be cut into three pieces so that the second piece is 3 times as long as the first piece and the third piece is 4 times as long as the first piece. The **length **of all the three pieces are : 7, 21, 18.

There are 3 pieces:

Length of first piece = x

Length of second piece = 3x

Length of third piece = 4x

Total length = 8x

Now, 8x = 56

Divide both side by 8x

x = 56 /8

x = 7

Length of **second **piece = 3x where x = 7

3x = 3 ( 7)

Which is the best estimate of the area of

the sign in square inches?

F 150 in.2

F

G 14 in.2

H 36 in.2

J 50 in.2

In order to determine the total area of the sign, we need to calculate the area of the triangle, and the area of the semicircle. The expressions we need to use are described below:

[tex]\begin{gathered} A_{\text{semicircle}}=\frac{\pi\cdot r^2}{2} \\ A_{\text{triangle}}=\frac{b\cdot h}{2} \end{gathered}[/tex]We were given the diameter of the semicircle, it's radius is half of the diameter, therefore:

[tex]r=\frac{6}{2}=3\text{ in}[/tex]The base of the triangle is equal to the diameter of the semicircle. With this we can calculate both areas:

[tex]\begin{gathered} A_{\text{triangle}}=\frac{6\cdot12}{2}=36\text{ square inches} \\ A_{\text{semicircle}}=\frac{\pi\cdot3^2}{2}=14.13\text{ square inches} \end{gathered}[/tex]The total area of the figure is the sum of the above, therefore:

[tex]\begin{gathered} A=A_{\text{triangle}}+A_{\text{semicircle}} \\ A=36+14.13=50.13 \end{gathered}[/tex]The area is approximately 50 in². The correct option is J.

Two planes, which are 2505 2505 miles apart, fly toward each other. Their speeds differ by 85mph 85 mph . If they pass each other in 3 3 hours, what is the speed of each?

When two planes which are 2505 miles apart and **fly toward each other**. if their **speeds **differ by 85mph and If they pass each other in 3 hours, then the speed of first plane is 372.5 mph and the speed of second plane is 462.5 mph

Their speeds differ by 85mph

Consider the speed of first plane = x mph

The speed of second plane = 90+x mph

**The relative speed** = sum of both speed

= x + x+90

= 2x+90 mph

**The distance **between the planes = 2505 miles

**Time taken** to pass each other = 3 hours

Therefore in 3 hours

3(2x+90) = 2505

6x+270 = 2505

6x = 2505-270

6x = 2235

x = 2235/6

x = 372.5 mph

The speed of second plane = 90+x

= 90+372.5

= 462.5 mph

Hence, when two planes which are 2505 miles apart and fly toward each other. if their speeds differ by 85mph and If they pass each other in 3 hours, then the speed of first plane is 372.5 mph and the speed of second plane is 462.5 mph.

The number of **hamburger** is 350 and the number of **cheeseburger** is 282.

It should be noted that an **expression** is simply used to show the relationship between the variables.

In this case, the local hamburger shop sold a combined total of 632 **hamburgers** and cheeseburgers on Saturday and there were 68 fewer cheeseburgers sold than hamburgers.

Let **Cheeseburger** = x

Hamburger = x + 68

This will be:

x + x + 68 = 632

2x + 68 = 632

2x = 632 - 68

2x = 564

x = 564/2

x = 282

Cheeseburger = 282

**Hamburger** = x + 68 = 282 + 68 = 350

The average teachers' salary in a certain state is $57,337. Suppose that the distribution of salaries is normal with a standard deviation of $7500. Assume that the sample is taken from a large population and the correction factor can be ignored. Use a TI-83 Plus/TI-84 Plus calculator and round the answer to at least four decimal places.What is the probability that a randomly selected teacher makes less than $50,000 per year?

Normal distribution of salaries

d = Standard dev = $7500 =

Correction factor= 0

Di

f(x) = (1/ d•√2π )• e ^- ((s- s')^2/2d^2)

Average value = u = 57337

Now calculate f(x)

Difference of salaries ,with respect to average

S^ 2= 57337 - 50000= = 7337

Now squared = (7337^2) = 53831569

d = 7500

2•d^2= 112500000
