Answer:
He would make $126.70 in 10 hours.
Step-by-step explanation:
First, you have to find the unit rate, in other words, how much money he earns in one hour. To do that, you have to divide.
38.00÷3= 12.666667
Once you know how much money Brandon earns in one hour($12.67), you multiply that number by 10.
12.67×10= 126.70
In conclusion, the answer to this solution($126.70) is how much money he earns in 10 hours.
Answer:
E, A, F
Step-by-step explanation:
Answer:
B. (1,5) and (5.25, 3.94)
Step-by-step explanation:
The answer is where the 2 equations intersect.
We need to solve the following system of equations:
y = -x^2 + 6x
4y = 21 - x
From the second equation:
x = 21 - 4y
Plug this into the first equation:
y = -(21 - 4y)^2 + 6(21 - 4y)
y = -(441 - 168y + 16y^2)+ 126 - 24y
y = -441 + 168y - 16y^2 + 126 - 24y
16y^2 + y - 168y + 24y + 441 - 126 = 0
16y^2 - 143y + 315 = 0
y = [-(-143) +/- sqrt ((-143)^2 - 4 * 16 * 315)]/ (2*16)
y = 5, 3.938
When y = 5:
x = 21 - 4(5) = 1
When y = 3.938
x = 21 - 4(3.938) = 5.25.
Simply plug g and h into the equation:
g + h =
(-7) + (3) = -4
