Answer:

d 13

Step-by-step explanation:

Subtracting means adding the opposite.

To subtract -4, you add the opposite of -4 which is 4, so you add 4.

9 - (-4) = 9 + 4 = 13

Answer: d 13

9-(-4)

Pretend that there is a -1 in front of the bracket

9-1(-4)

Mutiply the bracket by -1

(-1)(-4) = 4

9+4= 13

Answer : d 13

Answer:

Draw a line segment from (-7, -2) to (3, 8)

See the diagram below.

You do not have to draw the blue dashed line. It's there to show how the points reflect over.

=========================================================

Explanation:

The inverse will have us swap x and y. The point (x,y) becomes (y,x)

The endpoint (-2, -7) becomes (-7, -2)

Also (8,3) moves to (3, 8)

Visually, these points are being reflected over the line y = x to form the inverse. We only need to worry about the endpoints because 2 points is the minimum needed to form a straight line.

Check out the diagram below. The red segment is the inverse. The blue dashed line is the line y = x. You don't have to plot this line as it's just a visual tool to see what's going on. Your teacher likely will only want the red segment.

Since the original segment is parallel to y = x, the inverse is also parallel to the mirror line. All three lines are parallel.
