Add both the equations together to eliminate x
x+5y=8
-x+2y=-1
7y=7
y=1
Now fill in y into the original equation
x+5(1)=8
x+5=8
x=3
Now you can check by filling x and y into the second equation.
-(3)+2(1)=-1
-3+2=-1
-1=-1
So your answer will be (3, 1)

Step-by-step explanation:
Given data
C(x)=12x+114
R(x)=6x.
The company will start to run on profit just when revenue equals the production cost, that is
C(x)=R(x)
equating the two expressions we have
12x+114=6x
solving for x we have
12x-6x+114=0
6x+114=0
6x=-114
x=-114/6
x=-19
Hence the company will start to run on proft when they start to produce above 19 items
Answer: 3 + 15/16 inches
Step-by-step explanation:
You need (5 + 3/16) inches, and you have (9 + 1/8) inches, then the amount that you need to cut is equal to the difference between these numbers, this is:
(9 + 1/8) - (5 + 3/16) = (9 - 5) + (1/8 - 3/16) = 4 + (2/16 - 3/16) = 4 - 1/16
now, this notation is used for aditions, so we can write it as:
4 - 1/16 = 3 + 1 - 1/16 = 3 + 16/16 - 1/16 = 3 + 15/16
Then the amount that needs to be cuted is 3 + 15/16 inches
