Answer:

True, True, False, False, True

Step-by-step explanation:

Trapezoid ABCD was dilated to create trapezoid A'B'C'D'.

Scale factor is 1/2 according to the coordinates.

<h3>The answer options</h3>

<u>The length of side AD is 8 units.</u>

AD = 4 - (-4) = 8
True

<u>The length of side A'D' is 4 units.</u>

A'D' = 2 - (-2) = 4
True

<u>The image is larger than the pre-image.</u>

False. It is 2 times smaller.

<u>Sides CD and C'D' both have the same slope, 2.</u>

Slopes of CD and C'D' are same: m = (0 - 4)/(4 - 2) = -4/2 = -2

False

<u>The scale factor is One-half.</u>

True

If a =-2 and b= 2 what will be the value of a^b

raketka [301]

Write out the equation;

y=a^b
y=(-2)^2
y=(-2)(-2)
y=4

Therefore, the value of a^b is 4

Hope I helped :)

X+5 divided by 3=15 what is the answer?

GREYUIT [131]

All you have to do is solve for x. See the following steps below.

Step 1. Subtract $\frac{5}{3}$ from both sides

$X= 15-\frac{5}{3}$

Step 2. Simplify $15- \frac{3}{5}$ to $\frac{40}{3}$

$X= \frac{40}{3}$

18x26=? I don't get how to do this

elena-s [515]

Answer:

468

Step-by-step explanation:

Set it up like the following-

--------

108

360

--------

408

Take the right number (6) and multiply it with 18

6 x 18 = 108

Now do the same with 2, except put a 0 at the end

2 x 18 = 36

add 0

360

Add both numbers-

360 + 108 = 468

1 point<br> 5) Solve by using the quadratic formula 8x² = 15 - 14x

kykrilka [37]

<h3>I'll teach you how to solve 8x² = 15 - 14x</h3>

----------------------------------------------------

8x² = 15 - 14x

Add 14x to both sides:

8x^2 +14x =15-14x+14x

Simplify:

8x^2 +14x =15

Subtract 15 from both sides:

8x^2+14x-15 = 15-15

SImplify:

8x^2+14x-15 = 0

Solve with the quadratic formula:

x= $\frac{-14+ \sqrt{14^2-4*8(1-15)} }{2*8}$ = 3/4

x= $\frac{-14+ \sqrt{14^2-4*8(1-15)} }{2*8}$ = -5/2

The solutions to the quadratic formula are:

x= 3/4, x=-5/2

Your Answer Is x= 3/4, x=-5/2

plz mark me as brainliest :)
