Answer:
The answer is that x = -20.
Step-by-step explanation:
The equation:
5/2x + 1/2x = 10 + 7/2x
6/2x = 10 + 7/2x
-7/2x + 6/2x = 10
-1/2x = 10
-1/2x * -2 = 10 * -2
x = -20
Proof:
5/2*-20 + 1/2*-20 = 10 + 7/2(-20)
-50 + (-10) = 10 + (-70)
-50 - 10 = 10 - 70
-60 = -60
Answer:
42.47?
Step-by-step explanation:
Step-by-step explanation:
When x = -2, x + 2 = (-2) + 2 = 0.
The first one is quadratic function
