Answer:

Option C.

Step-by-step explanation:

Two trapezoids W'X'Y'Z' and WXYZ have been given in the figure attached.

Trapezoid WXYZ has been dilated to form another trapezoid W'X'Y'Z'.

We have to find the scale factor by which WXYZ was dilated.

Dilation factor = \frac{\text{Trapezoid W'X'Y'Z'}}{\text{Trapezoid WXYZ}} = \frac{W'X'}{WX}

= \frac{6}{8}

= \frac{3}{4}

Therefore, \frac{3}{4} is the dilation factor by which trapezoid WXYZ was dilated.

Option C is the answer.

Which expression is equivalent to 60 - 3y - 9?
disa [49]

Answer:

the answer has to be 3(17-y)

Step-by-step explanation:

I'm pretty sure about that cause what I did at first is subtract the numbers.

<em>6</em><em>0</em><em>-3y-9</em>

=51-3y

factor our 3 from the expression.

3(17-y)

How to graph y=3x+44
Andre45 [30]

This is in slope intercept form, which tells us directly where the y-intercept is, and what the slope is.

y=mx + b

m = slope

b = y-intercept

So, the y intercept is (0, 44)

And the slope is 3, or 3/1

Find the coordinates of the fourth vertex that completes the construction of the rectangle on the coordinate plan
SOVA2 [1]

The coordinates of the fourth vertex are (2, -4).

Step-by-step explanation:

Step 1:

The opposite sides of a triangle are always equal.

First, we plot the three given points of the rectangle.

Assume the top left corner is A, the top right corner is B, the bottom left corner is C and the bottom right corner is D.

We need to determine the coordinates of point D.

Step 2:

The coordinates of the given three points are

A (-2, 5), B (2, 5), and C (-2, -4).

A and C are the same side i.e. the left side, they have the same x coordinate of -2.

So B and D will have the same x coordinate of 2.

A and B are on the same side too i.e. the top side so they both have the same y coordinate of 5.

The points C and D are two ends of the bottom side so they must have the same y coordinate of -4.

So the coordinates of the fourth vertex are (2, -4).

Evaluate this exponential expression.
Levart [38]

Answer:

(-27)^\dfrac{2}{3} = 9

Step-by-step explanation:

Given that,

Asn expression : (-27)^\dfrac{2}{3}

We need to evaluate the above expression.

We know that, (-3)^3=-27

So,

(-27)^\dfrac{2}{3}=(-3)^{3\times \dfrac{2}{3}}

or

=(-3)^2\\\\=-3\times -3\\\\=9

So, the value of (-27)^\dfrac{2}{3} is 9. Hence, the correct option is (b).
