Solve for x in the second equation first
Slope intercept: y = mx + b
Y = 5x + b
10 = -20 + b, b = 30
Equation: y = 5x + 30
Answer:
Step-by-step explanation:
The two photos are attached for the missing information in your question.
Statement: m∠7 and m∠8 are supplementary.
Reason: Linear Pair Theorem
Not enough data given here. Incomplete question.
Beginning with the function y = sin x, which would have range from -1 to 1 and period of 2pi:
Vertical compression of 1/2 compresses the range from -1/2 to 1/2
Phase shift of pi/2 to the left
Horizontal stretch to a period of 4pi, as the crests are at -4pi, 0, 4pi
Vertical shift of 1 unit up moves the range to 1/2 to 3/2
So the first choice looks like a good answer.
