Answer:
D
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (8, - 1), thus
y = a(x - 8)² - 1
To find a substitute (0, - 17), the coordinates of the y- intercept into the equation.
- 17 = a(0 - 8)² - 1
- 17 = 64a - 1 ( add 1 to both sides )
- 16 = 64a ( divide both sides by 64 )
a =
= - 
y = -
(x - 8)² - 1 → D

Answer:
2
Step-by-step explanation:
22 - 2y
= 22 - 2 ( 10 )
= 22 - 20
= 2
Answer:
Assuming the asterisks are exponents, then OD and exponential equation has to have both a multiplier(exponent).
Step-by-step explanation:
Is the greatest factor that two or more numbers have in common. One way to find the GCF is to make lists of the factors for two numbers and then choose the greatest factor that the two factors have in common.
