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>

The length of side AD is 8 units.

AD = 4 - (-4) = 8
True

The length of side A'D' is 4 units.

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

The image is larger than the pre-image.

False. It is 2 times smaller.

Sides CD and C'D' both have the same slope, 2.

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

False

The scale factor is One-half.

True

Two numbers are in the ratio 3: 7. If 1 is added to the smaller number and 7 is added to the larger, they will be in the ratio 1

pashok25 [27]

Answer:

6 and 14

Step-by-step explanation:

The numbers are in the ratio 3 : 7 = 3x : 7x (x is a multiplier )

adding 1 to smaller number is 3x + 1 and 7 to the larger is 7x + 7, then

3x + 1 : 7x + 7 = 1 : 3

Expressing the ratio in fractional form

$\frac{3x+1}{7x+7}$ = $\frac{1}{3}$ ( cross- multiply )

3(3x + 1) = 7x + 7

9x + 3 = 7x + 7 ( subtract 7x from both sides )

2x + 3 = 7 ( subtract 3 from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

Thus the numbers are

3x = 3(2) = 6

7x = 7(2) = 14
