Answer:

D. -8

Step-by-step explanation:

An x intercept is where the y value is zero.

We set the expression equal to zero and solve for x.

x^2 - 64 = 0

(x + 8)(x - 8) = 0

x + 8 = 0 or x - 8 = 0

x = 8 or x = 8

Answer: D. -8

Given the following geometric sequence, find the common ratio: {3, 18, 108, ...).
vodomira [7]
Geometric sequences go up due to a common ratio. Here the common ratio can be worked out by dividing a term by its previous term e.g term 2 divided by term 1.

18/3 = 6


Therefore the common ratio is 6.

A. Transform F using the rule (x, y) → (-x, y) (1 pt.)
serg [7]

Answer:

A: (-3,4) (-3,6) (-5,6) (-7,4)

B: The transformation would be described as a reflection over the y axis

C:  The transformation does result in a congruent figure because the shape doesn't change in size or shape and in length or width

Step-by-step explanation:

So our plots from the figure are: (3,4)  (3,6)  (5,6)  (7,4)

So using the rule (x, y) → (-x, y) are new points would be:

(-3,4)

(-3,6)

(-5,6)

(-7,4)

This rule (x, y) → (-x, y) is used for the type of transformation that is a reflection but over the y axis.
