Answer:
h= -6
Step-by-step explanation:
-8-h=2(-.5h+4)
-8-h=h+4
-2h=12
h=-6
We can create the equation like this:
(x +2) * (x +0)
x^2 + 2x + 0 = 0
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
the scale is x4
because 10x4=40
11x4=44
18x4=72
you multiply by 4 on all of them
Answer:
Option B
Step-by-step explanation:
Lets open the brackets of L.H.S.
Lets substract q² from both the sides.
Lets divide both the sides by q.
