Answer:

  8. yes

  9. no

  10. yes

Step-by-step explanation:

8. A horizontal line (y=3) is perpendicular to a vertical line (x=0).

__

9. A horizontal line (y=2) is parallel to a horizontal line (y=-1/2). The lines are not perpendicular.

__

10. A parallelogram is a rectangle if the sides are perpendicular. The slopes of the short sides are rise/run = -1, and the slopes of the long sides are rise/run = +1. These values have a product of -1, so the sides are perpendicular. The figure is a rectangle.

What is the slope? ​
Luda [366]

Answer:

-3

Step-by-step explanation:

Find two easy to read points on the graph.

I see (0, 1) and (-1, 4).

slope = rise/run

Start at (0, 1). Go up 3 units. That is a rise of 3. Now go left 1 unit. That is a run of -1.

slope = rise/run = 3/(-1) = -3

Answer:

  D. x to the power of nine

Step-by-step explanation:

The applicable rule of exponents is ...

  (x^a)^b = x^(ab)

You have a=3/2, b=6, so ab = 3/2·6 = 9.

  (x^(3/2))^6 = x^(3/2·6) = x^9

Solve algebraically: <br> Y = x^2 + 5x - 17 <br> Y = x - 5
Ksenya-84 [330]

Answer:

2

Step-by-step explanation:

What you could do is fill in 2 for the equation and y would equal -3 so for the first one it's like

y= 2^2 + 5(2) -17

y= 4 + 10 - 17 which turns into y= -3

In the second y it would be something like

y= 2 - 5 which would equal y= -3

so x=2
