Answer:
The answer is 88.
She would have to score 88
Step-by-step explanation:
86 + 88 = 174
174 ÷ 2 = 87
T (-1, 3) is vertically 2 units away from the line y = 1.
When finding the ordered pair for the new point, M, it must also be 2 units from the line y = 1, but on the opposite of the line. The x-value will not change only the y-value.
Counting two units BELOW the line we get M(-1, -1)
Just divide 18 by 20 , so its 0.9
X is equivalent to 200. (credit to suspho)
