Answer:
(136.60 - 61.60) / 30 = 2.5 hours
Step-by-step explanation:
First, subtract the cost of parts from the total: 136.60 - 61.60 = 75
Now you have the total labor cost. Divide by the hourly rate: 75 / 30 = 2.5
Answer:
Resulting plot in the image attached
Step-by-step explanation:
Start by making a table of (x,y) pairs that satisfy this equation. Notice that two pairs would be enough, but it is always safer to obtain at least three to see them actually "aligned".
We are trying to find values for y when x= 0, 2, and 4 to make our calculations simple:

When x = 0 then:
So we plot the value (0,-3) on the x-y plane.
When x = 2 then:
So we plot the value (2,-2) on the x-y plane.
When x = 0 then:
So we plot the value (4,-1) on the x-y plane.

Answer:
It should be D.
Step-by-step explanation:
the correct given statement should be the first option "Plane R is parallel to plane S; Plane T cuts planes R and S." as it precisely reflects the statement above. The other options deal with triangles and point and are not relevant.
