Answer:
85
Step-by-step explanation:
2(-4)^2=32
-10(-4)=40
32+40+13=85
We have that with the increase made Brooke now earns the following amount per hour:
(7 + 1) = 8 $ / h
Therefore we must now rewrite the weekly expression of your earnings.
Rewriting we have:
(7 + 1) r =
8r
Answer:
the amount Brooke would make in a week after the raise is:
8r
Answer:
-1 > x and x > 7.
Step-by-step explanation:
-12 < -3x - 15 < -36
What we are looking at here is a comparison with -12 being the smallest value, -3x - 15 being the second smallest value, and 36 being the largest value in the sequence. What you need to do is to make the problem into two separate problems:
-12 < -3x - 15
and
-3x - 15 < -36
Then we solve the equations like so (using PEMDAS):
-12 < -3x - 15
+15 +15
3 < -3x
/-3 /-3
-1 > x (the sign was changed the other way because when you divide by a negative it has to be flipped)
Now the other equation
-3x - 15 < -36
+15 +15
-3x < -21
/-3 /-3
x > 7
Now we have the inequalities of -1 > x and x > 7.
The answer is 9t because 9 times 6 is = 54
