The red arrows show that the lines are parallel, but using the stuff given you can make an equation.
its hard to explain without drawing but starting from the 60 if you can make a Z you will get alternate angles and that mean that the given equation MUST be equal to 60. So,
8x-4=60
8x=60+4
8x=64
x=64/8
x=8 (is your answer)
hope you understand
60200 since the three rounds down
So first you would divide the 9 on both sides then 6 divided by 9 would be .6 repeating so m=.6 repeating.
The domain is the origin of the arrow
domain = {-2,2,3,4}
Option d is the answer
