Hey there!

The unit rate is 8.30 for every hour.
If he earns $8.30 an hour and works 9 hours, multiply 8.30 by 9.
8.30 x 9 = 74.70
Hope this helps!
By plunging 5 into the equation as x, you have the equation
7(5) - 15
7 * 5 = 35 so
35 - 15
f(5) = 20
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

Parallel lines have the same slope. Therefore if given line is

then the slope of our line is
.
We have the equation:

The line passes through (-1, -7). Put the coordinsted pf the point to the equation:

<em>add 2 to both sides</em>

Finally:

Triangle Area = .5 * (base * height)
36 = (base * height) / 2
So let's say base = 9 height 8
If base and height are scaled by a factor if 5 than
base = 45 height 40 and
area = .5 * (45 * 40)
area = 900
Basically, the area increases by a factor of 25.
The base increases by 5 and the height increases by 5 so the area increases by 5*5 = 25
