Answer:
c = 8.25
Step-by-step explanation:
c + 30 +2 = 5c -1 (collect like terms ex: 1+2 are like terms = 3)
c + 32 = 5c - 1 (subtract c on both sides)
32 = 4c - 1 (add one on each side)
33 = 4c (divide by 4 on both sides)
8.25 = c

Answer: u mean r=0
- 5/2
Arrange this line equation into y = mx + b form m = slope
y = 2/5x + 12/5
then perpindicular line = - 1/m = - 1/ (2/5) = - 5/2
-3(x+2)-7 = 5x + 7
-3x - 6 - 7 = 5x + 7
-3x - 13 = 5x + 7
-20 = 8x
x = -2.5
Option A is the answer
