Answer:
For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)
Step-by-step explanation:
Given expressions are;
4(5x-8) and 2(4-x)
For 4 more than the second expression, we will add 4 with second expression.
4(5x-8) = 2(4-x) + 4
20x - 32 = 8 -2x +4
20x + 2x = 12 + 32
22x = 44
Dividing both sides by 22
![\frac{22x}{22}=\frac{44}{22}\\x=2](https://tex.z-dn.net/?f=%5Cfrac%7B22x%7D%7B22%7D%3D%5Cfrac%7B44%7D%7B22%7D%5C%5Cx%3D2)
Hence,
For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)
Answer:
18 and 19
Step-by-step explanation:
Given that,
Total cost function, C (x) = 43x + $1850
The revenue function R (x) = $80x
To find,
The number of units that must be produced and sold to break even.
Solution,
At break even, cost = revenue
43x + $1850 = $80x
Subtract 80x from both sides.
43x + 1850 -80x = $80x -80x
1850 = 80x-43x
37x = 1850
x = 50
So, the required number of units are 50.
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
