Answer:
y = 2/5 x - 18/5
Step-by-step explanation:
y = mx + b
m = (y2 - y1)/(x2 - x1) = [-2 - (-6)]/[4 - (-6)] = 4/10 = 2/5
y = 2/5 x + b
-6 = (2/5)(-6) + b
-30 = -12 + 5b
5b = -18
b = -18/5
width = w
length = 2w
perimeter = 2w + 2 l
perimeter = 2w +2(2w)
60 = 2w + 4w
60= 6w
60=6w
w = 60/6 = 10
length = 10x2 = 20
10+10+20+20 = 60
x=36
Divide the corresponding side (16) by 4/7
The answer is B.
9 : 12 = 3 : 4
12 : 16 = 3 : 4
