R =
I think “represent” is asking you to solve to a number.
10r + 4 = 8
Subtract 4 from both sides of the equation:
10r = 4
Divide both sides by 10:
r = 0.4
Check the math:
10(0.4) + 4 =
4 + 4 = 8
Answer:
B. 2
Step-by-step explanation:
The number next to the variable is the coefficient. So, it is 2
Distribute the signs: 12-14+9x
so, -2+9x
Every point in the unit circle is identified either by its coordinates 
or by the angle it forms with the x-axis, 
.
The trigonometric functions associate with every angle and the correspondant coordinates the two values
This procedure can be done for every angle , so you don't have to work with acute angles only.
You can only cut down a integer number of trees. So you might look at a few integer values for x. As x get large the –x4 term dominates the expression for big losses. x = 0 is easy P(x) = -6. Without cutting any trees you have lost money Put x = 1 and you get for the terms in order -1 + 1 + 7 -1 -6 = 0. So P(x) crosses zero just before you cut the first tree. So you make a profit on only 1 tree. However when x=10 you are back into no profit. So compute a few values for x = 1,2,3,4,5,6,7,8,9.
