Answer:
4
Step-by-step explanation:
All the sides of an equilateral triangle are equal, hence the perimeter is expressed as P = 3s
s is one of the side length
Given DE = 5x - 8
P = 3DE
P = 3(5x-8)
36 = 3(5x-8)
36/3 = 5x-8
12 = 5x - 8
5x = 12+9
5x = 20
x = 20/4
x = 4
Hence the value of x is 4
Answer:
y=-4/3 + 11
Step-by-step explanation:
1. Find the slope
<u>3-(-1) </u>
-6-(-3)
slope= -4/3
2. Point slope form
y-3=-4/3(x+6)
y-3=-4/3x + 8
y=-4/3x+11
