c.) x = 9⁰, angle measure is 27⁰
Answer:
B: $2.50
Step-by-step explanation:
Step 1: form an equation
126 = 12(8 + x)
Step 2: isolate the x
126/12 = 8 + x
126/12 - 8 = x
Step 3: solve
10.5 - 8 = x
2.5 = x = raise per hour
I’m not so sure I fully understand the question. But I would say the rate is 1.
I say this because the line on your graph is a y=mx+b equation.
For every unit it moves over on the X axis it moves the same unit on the Y axis.
I hope this helps.
It would go in between 8 and 10 since the scale goes by 2's and 9 is in between 8 and 10. Hope this helps you!
