Answer:

y = 3/2x - 7

Step-by-step explanation:

slope-intercept: y = mx + b

m = slope (3/2)

b = y-intercept (-7)

when put together, the equation is y = 3/2x - 7.

Answer:

A. 4 trucks will make $80 because 4 × 20 = 80, so they need to wash 38 cars to make the other $380 because 38 × 10 = 380.

($80 + $380 = $460)

B. 15 trucks will make $300 because

15 × 20 = 300, so they need to wash 16 cars to make the other $160 because 16 × 10 = 160. ($300 + $160 = $460)

C. 21 trucks will make $420 because

21 × 20 = 420, so they need to wash 4 cars to make the other $40 because 4 × 10 = 40.

($420 + $40 = $460)

D. 27 trucks will make $540, so they won't have to wash any cars because they would have already exceeded their goal of $460.

Not sure what to do for letter E. Sorry. I hope the rest makes sense though :)

What are my zeros (x^2 - 8x + 1)?

Pavel [41]

Answer:

x= 7.87298334621 x=.12701665379

Step-by-step explanation:

This is in standard form so we have to factor this into

x^2-8x + 16 + 1 = 16

(x-4)^2 = 15

(x-4) = $\sqrt{15\\}$

x-4= ± 3.87298334621

x-4 = 3.87298334621 x-4= -3.87298334621

x= 7.87298334621 x=.12701665379

<h3>What is a line graph?</h3>

A line graph is a graph that is used to represent numerical data. It shows the changes in the data with the passage of time. There are two axes on a line graph, the vertical axis and the horizontal axis. The range of the vertical axis should start from 0 and end at the largest number of data set.

The width of a rectangle is 7 less than the length. If the perimeter of the rectangle is 43.6 inches, what is the area of the re

Lera25 [3.4K]

Call the length a, the width b

Perimeter = (a+b) x 2

And since we have (a+b) x 2 = 43.6, a + b = 43.6 : 2 = 21.8

a + b = 21.8
a - b = 7

-> a + b + (a - b) = 28.8
2a = 28.8
a = 14.4
b = 7.4

So, the area of the rectangle is 14.4 x 7.4 = 106.56
