Answer: x = 
Step-by-step explanation:
Answer:
D. Their intersection point is the only point where the same input into both functions yields the same output.
Step-by-step explanation:
The intersection point of 2 graphed lines represents the solution.
At this point, for both lines, there is the same x value (input) and the same y value (output) because both of the lines have that point in common.
So, if those 2 lines were to be graphed, the intersection point would represent the only point with the same input and output for both functions.
D is the correct answer.
both angles would equal the same so you have:
6x-57 = 2x+15
add 57 to each side:
6x = 2x+72
subtract 2x from each side:
4x = 72
divide:
x = 72/4 = 18
now replace x with 18:
6(18) - 57 = 51
2(18) +15 = 51
51 +51 = 102
Angle QNR = 102 degrees
40 - 4 = 36
average = 36/9 = 4
