Answer:
mean is 5
Step-by-step explanation:
Yes, 4 times 3 is 12, 12 times 5 is 60
x- coordinate of vertex = - 3
the vertex lies on the axis of symmetry , which is positioned at the midpoint of the zeros
find the zeros by setting y = 0
(x - 6)(x + 12) = 0 ( equate each factor to zero and solve for x )
x - 6 = 0 ⇒ x = 6
x + 12 = 0 ⇒ x = - 12
x coordinate of vertex =
=
= - 3
Answer:
3. y = 8x
Step-by-step explanation:
y = 8x
earnings (y)=$8×number of hours (x)
8 dollars is her hourly wage and that multiplied by the number of hours she works will give you her total earnings.
Hope this helps! :)
