Step-by-step explanation + Answer:
x = 1st job
y = 2nd job
x + y = 22......x = 22 - y
7x + 8.25y = 171.50
7(22 - y ) + 8.25y = 171.50
154 - 7y + 8.25y = 171.50
-7y + 8.25y = 171.50 - 154
1.25y = 17.50
y = 17.50 / 1.25
y = 14 <== 14 hrs at the 8.25 per hr job
x + y = 22
x + 14 = 22
x = 22 - 14
x = 8 <=== 8 hrs at the 7 per hr job
Answer:
First of all which question are you asking me to do?
Second of all you can also just ask a parent/guardian to help you.
Answer: 10
Step by Step Solution:
You have x and y as your axis’s and that as your table with x being time and y being percent bounded. As for that you got (0, 0) and (5, 50).
Then you plug those numbers into the equation to finding slope: m = y2 - y1 / x2 - x1 to have m = 50 - 0 / 5 - 0
Then you have to simply the equation to have m = 50 / 5 and then you divide them as the line of a fractions means division and you will have m = 10
(3,-2)
-4 + 7 units to the right = 3
2 - 4 units down = -2
prime factor stuff.. 32 = 8*4 = (4*2)*(2*2) = (2*2*2)*(2*2)
3 √(2*2*2*2*2*x*x*x*x*z) = 3 √(2²*2²*2*x²*x²*z)
It's a square root so move one of each pair outside the radical.
3*2*2*x*x √(2*z)
12x² √(2z)
