Use slope formula to find slope −9−5−/12−8=−14/−20=7/10 7/10 = m = slope
y= mx + b
y= (7/10)x + b
(8,5)
(5) = (7/10)(8) + b
b = -3/5

So.... y=(7/10)x −35

 multiply by 10

10y=7x−6 --> -7x + 10y = -6
--> 7x - 10y = 6
So, if 7x - 10y = 3 a good model?

A rectangular painting measures 15 inches by 18 inches and contains a frame of uniform width around the four edges. The perimete

vfiekz [6]

Answer:

3 inches

Step-by-step explanation:

Lenght = 18 inches

Width =15 inches

Perimeter of the rectangular painting and frame = 90 inches

Let X be the width of the frame

The width of the framed picture = 15 + 2x

The length of the framed picture = 18 + 2x

Perimeter = 2 (L + W)

90 = 2(15 + 2x + 18+ 2x)

90 = 2(33 + 4x)

90 = 66 + 8x

8x = 90 - 66

8x = 24

x = 24/8

x = 3 inches

the width of the frame is 3 inches
