Answer:
(-2,-1)
Step-by-step explanation:
Reflection across the x-axis is:
We need to multiply the y-value of the pre-image by negative one to get reflected across the x-axis.
1 * -1 = -1
So:
D' should be (-2,-1).
7ft = 84in 84 ÷ 15 = 5.6 pieces he can cut from each board. Since .6 is not a whole piece measuring 15 inches long, he can only cut 5 pieces from each board.
So, 5 x 2 = 10
He would be able to cut 10 pieces measuring 15 inches long.
