Answer:

(6,-6)

Step-by-step explanation:

First let's identify the current coordinates of D

It appears that D is located at (2 , -2)

Now let's find the coordinate of D if it were dilated by a scale factor of 3.

To find the coordinates of a point after a dilation you simply multiply the x and y values of the pre image coordinates by the scale factor

In this case the scale factor is 3 and the coordinates are (2,-2)

That being said let's apply the dilation rule

Current coordinates: (2,-2)

Scale factor:3

Multiply x and y values by scale factor

(2 * 3 , -2 * 3) --------> (6 , -6)

The coordinates of D' would be (6,-6)

Take west to be the positive direction. The height of a sloped roof above the place where you stand is 12

<u>Given:</u>

Take west to be the positive direction. The height of a sloped roof above the place where you stand is 12 feet. If you move 3 feet west, the height is 10 feet.

We need to determine the slope.

Let x denote the standing place.

Let y denote the height.

Writing the given as coordinates, we get;

(0,12) and (3,10)

<u>Slope</u>:

The slope can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the coordinates (0,12) and (3,10), we have;

$m=\frac{10-12}{3-0}$

$m=\frac{-2}{3}$

Thus, the slope is $m=-\frac{2}{3}$

What number is x if the equation is 2x-7=3

Elanso [62]

Hello there!

2x - 7 = 3

Solve for x

2x = 3 + 7

2x = 10

x = 10/2

x = 5

Therefore, the number of x in the equation is 5

Let me know if you have additional question!
