20 hours times $9 is $180. She would have to work over 20 hours to earn more than $180.
I would say 21 hours.
Statement 1 is false.
While it is true that some of the y-values have more than one corresponding x-value, this does not make the relation not a function. It would not be a function if some of the <em>x-values</em> had more than one corresponding y-values.
Statement 2 is true.
The domain of a function is all the x-values it encompasses. This function starts at 3 and ends at 8.
Statement 3 is false.
The range of a function is all the y-values it encompasses. This includes all the y-coordinates, but it does not express the range properly. The range is [6, 10].
Hope this helps!!

Actually Welcome to the concept of straight lines.
==> y-y1 = m(x-x1)
==> y = mx+c
these two are the straight line equation, so we get as,
=> 0-0 = m(8-(-7)
==> 0 = m(15)
==> hence, 15m = 0
Answer:
m = 4
Step-by-step explanation:
m−10+6m=10+2m
7m-10=10+2m
<em>Subtract 2m from both sides</em>
5m-10=10
<em>Add 10 to both sides</em>
5m=20
<em>Divide both sides by 5</em>
m=4
