First, find the y-intercept of the line y=-2x+7. When x=0 you have that y=-2·0+7, y=7, then point (0,7) is the y-intercept.

When you rotate this line 90° clockwise about the origin, then point (0,7) will be placed on the x-axis in positive x-direction. Rotation preserves the distances, then the coordinates of the image are (7,0).

Answer: correct choice is D.

2 (k - 5) + 3k = k + 6
PolarNik [594]

Answer:

k=4

Step-by-step explanation:

First, distribute the 2 on the left side

2 (k - 5) + 3k = k + 6

2*k +2*-5 +3k=k+6

2k-10+3k=k+6

Combine like terms on the left side

5k-10=k+6

Add 10 on both sides

5k=k+16

Subtract k on both sides

4k=16

Divide by 4 on both sides

k=4

Hope this helps! :)
