A dilation means that a shape is expanded or shrunk by a scale factor. The scale factor is 4, so all the points are multiplied by 4 to reflect this expansion.

A reflection over the y-axis means that the y-values in the points change their sign from positive to negative, and vice versa.

Therefore, the points will become the following:
A''(12,-12), B''(-4, -12), C''(-16,-4), D''(0, -4)

This new shape will be similar to the original shape, since it shares the same shape, but not the same size.

The answer is A.

1. What is the value of x in the equation 4x – 2(x + 3) = 8? (LT 1a)
german

Answer:

D

Step-by-step explanation:

4x - 2(x + 3) = 8

Use distributive property

4x -2x - 6 = 8

2x - 6 = 8

2x = 8 + 6

2x = 14

x = 14 ÷ 2

x = 7

-X + 5 = 1<br> What is the answer for this equation and the steps
jekas [21]

Answer:

x=4

Step-by-step explanation:

-x=1-5 (subtract 5 from both sides to isolate the x variable)

-x= -4 (1-5= -4)

x=4  (divide both sides by -1 so the x will not be a negative.)

Therefore, your answer will be x=4. Hope this helps! :)

What is x? I tried it but I don’t think I did it right.
sattari [20]

Answer:

x = 4

Step-by-step explanation:

When a tangent and a secant are drawn from an external point to a circle.

Then the product of the external part of the secant and the entire secant and the square of the measure of the tangent are equal, hence

x(x + 5) = 6²

x² + 5x = 36 ( subtract 36 from both sides )

x² + 5x - 36 = 0 ← in standard form

(x + 9)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

x - 4 = 0 ⇒ x = 4

However, x > 0 ⇒ x = 4
