Answer:
y = 120
Step-by-step explanation:
this is the formula
y = kx
now insert the numbers to find k
120 = k8
120/8
k = 15
now insert 15 into the equation where k was
y = 15 x 14
y = 210
Answer 2x^3+9
Explanation: evaluate the exponent
9+4^2/8•x^3
9+16/8•x^3
Divide the numbers
9+16/8•x^3
9+2x^3
Rearrange terms
9+2x^3
2x^3+9 and that’s the answer;)
The answer is 2z-10. Hope it helps.
