so -2 (12k^2 - 3)
-24k^2 +6
back into the problem,

Hope this helps :)
Answer:
y-1=0
Step-by-step explanation:
To rewrite the equation 5x - 8y + 3 = 5x - 7y + 2, combine like terms across the equal sign using inverse operations.
5x - 8y + 3 = 5x - 7y + 2
5x - 5x - 8y + 3 = 5x - 5x -7y + 2
-8y + 3 = -7y + 2
-y +3 = 2
-y = -1
y- 1 = 0
Profit would be the revenue minus the cost
so R=x^3-6x^2 +x +75 - C=x^2-70x =
see picture for answer
Subtract the rental fee, then divide the left over amount by the cost per hour.
