<span>f(x)=6x^3-3
1. Replace f(x) with y: y = 6x^3 - 3
2. Interchange x and y: x = 6y^3 - 3 x+3 x+3
3. Solve this result for y: y^3 = --------- or y = cube root of -------
-1 6 6
4. Replace y with f (x)

D) 5 is the answer
Assuming AE and CE are the same length you would set the two equations to each other: 8x+7=11x-8
Then solve for x:
Subtract 8x from both sides and add 8 to both sides looking like: 15=3x
Divide by 3 to get x by itself and you get x =5
CATERING TOTAL COST F(X) = 10X + 300
TOTAL REQUIRED 14X
10X + 300 = 14X
10X - 14X = -300
-4X = -300
4X = 300
X= 300/4
X=75 <------------------SOLUTION
Follow these steps to convert fraction to a mixed number
First Multiply the whole number part by the fraction's denominator.
Then add it to the numerator.
Then write the results on top of the denominator.
07/13 = 10713 = 8 3/13
The answer that I got is
8 3/13
I hope it helps
