Answer:
Vertex: (5, -9)
Step-by-step explanation:
fix = (x-8)(x-2)
fix = x^2 - 2x - 8x + 16
fix = x^2 - 10x + 16
a = 1, b = -10, and c = 16
To find vertex:
x = -b/2a
x = -(-10)/2(1)
x = 10/2
x = 5
y = 5^2 - 10(5) + 16
y = 25 -50 + 16
y = -9
Vertex: (5, -9)
Answer:30
Step-by-step explanation:the initial statement is
y ∝ x
to convert to an equation multiply by k the constant
of variation
⇒ y = k x
to find k use the given condition
y = − 24 when x = 8 y = k x ⇒ k = y x = −22
∣
∣
∣22 y = − 3 x 22
∣∣∣
−−−−−−−−−−−−−−
when x = 10
then y = − 3 × 10 = −30
The answer is a. -9, -4, 5, 6.
