Answer:
(x + 8) / 4 = (x - 3) / 2 | *4
x + 8 = 2 * (x - 3)
x + 8 = 2 * x - 6
8 = x - 6
14 = x
The number is 14.
(14 + 8) / 4 = (14 - 3) / 2
22 / 4 = 11 / 2
5.5 = 5.5
Divide x by y and compare:
5/1 = 5
10/2 = 5
20/4 = 5
All 3 are the same number so yes the rate of change is constant.
Answer: -x + 4y
Step-by-step explanation:
-3(2x-y) + 2y+2(x+y)
-6x + 3y + 2y + 2x + 2y
-6x + 2x +3y + 2y + 2y
-6x + 5x + 4y
-x + 4y
