Its D.
First you find the slope which is (picking any points)
y2-y1/x2-x1

0-4/2-1....slope is -4

using the 
y = mx+b plug in points
0 = -4(2) + b
0 = -8 +b
b = 8

ratio of a rectangle's length to its width is 4:7. If the longer side is 31.5in., find the width, the perimeter, and the area of
Nikitich [7]

Answer:

Step-by-step explanation:

Ratio of length : width = 4 : 7

Length = 4x

Width = 7x

Longer side = 31.5 in

⇒ 7x = 31.5

Divide both sides by 7

x = 31.5/7

x = 4.5

length = 4x

           = 4*4.5

         l = 18 in

width =  31.5

       w = 31.5 in

\boxed{ \text {Perimeter of  rectangle }= 2*l + 2*w}

                                      = 2*18 + 2*31.5

                                      = 36 +  63

                                      = 99 in

\boxed{ \text{Area of rectangle = l*w}}

                             = 18*31.5

                             =  567 in²

What is the answer to 8x + 8y + 12
umka21 [38]
Simplifying
8x + 8y = 12

Solving
8x + 8y = 12

Solving for the variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8y' to each side of the equation. 8x + 8y + -8y = 12 + -8y

Combine like terms: 8y + -8y = 0
8x + 0 = 12 + -8y
8x = 12 + -8y

Divide each side by '8'.
x = 1.5 + -1y

Simplifying x = 1.5 + -1y

hram777 [196]

Answer:

The predicted GPA is then y = 0.149(15) + 0.89 = 3.1

Step-by-step explanation:

Although you don't specifically say so, the equation you provide here is probably a "best fit" equation based upon data:  GPA versus the number of hours of study per week.

y = 0.149x + 0.89 and the number of study hours of interest is 15.
