Answer:
No solution
Step-by-step explanation:
Given equation is,
if x ≠ ±1
[Squaring on both the sides of the equation]
4 = (1 - x)(4 + x)
4 = 4 - 4x + x - x²
0 = -3x - x²
x² + 3x = 0
x(x + 3) = 0
x = 0, -3
But both the solutions x = 0 and x = -3 are extraneous solutions, given equation has no solution.
.50 x 15 = 7.5. This is the total amount of miles he was charged.
7.5 + 3.00 (the base charged) = 10.50
I don’t understand what it wants exactly does it want the average? The average is 108.92
