Answer:
C
Step-by-step explanation:
First you find which line is which.
The one with 5x in it is the steepest one, and we have to be above it due to the >.
The one with 2x in it is the least steep, and we have to be below it due to the <.
Graph C satisfies both these restrictions.
Given:
6/7(7/6z)
First, you would have to multiply both fractions together:
6/7(7/6z) = 42/42z
Next, simplify:
1z
(Since 42/42 is a bit redundant, you would then simplify to 1z)
Finally, you can either leave the answer as 1z or you can just leave it as z, because in math, variables have an imaginary 1 in front of them so the 1 is not necessary.
Answer: z
I hope this helps!
