There are no coordinates for an equation like this, you have to just graph the problem. Just try graphing something similar to this (or just include this image). Hope this helps!
Answer:
I don't know soorry. lalalala
Z = 3 (This equation is a given)
z(y) = 12 ( This equation is also given)
3y = 12 (as z = 3, plug 3 into z)
3y/3 = 12/3 (isolate the y by dividing 3 to both sides)
* you divide 3 to both sides because of the equal sign. What you do to one side you do to the other
y = 4 (answer for y)
y + 5 (what you are solving for)
(4) + 5 = 9 (As y = 4, plug in 4 for y in this equation)
y + 5 = 9 (4 + 5 = 9, or addition property)
9 is your answer
hope this helps
15x = 3x + 120 (subtract both sides by 3x)
12x = 120 (divide both sides by 12)
x = 100
Multiply the probability by the cost of the accident:
14,886.05 x 0.071 = 1056.91
Now add the overhead cost:
1056.91 + 110 = 1166.91
The closest answer to this is number D.
