Answer:
x*15% (x times fifteen percent)
Step-by-step explanation:
Say x is 20, you multiply 20 times 15% and that will be your answer
Answer:
x = 7
Step-by-step explanation:
y = (x – 7)^2 – 3
This equation is in vertex form
y = a(x-h)^2 +k
where (h,k) is the vertex
For a vertical parabola, the line of symmetry is x=h
x = 7
C. multiplication (the 8 x 9 within the parenthesis)
