Answer:
At x = 2 and 10.
Step-by-step explanation:
Given : The cost of producing x hundred items is given by the equation 
The revenue generated from sales of x hundred units is given by the equation 
To Find :What values of x will the company break even?
Solution:
Cost function : 
Revenue function : 
Now to find the company break even :







So, x = 2,10
Hence the company break even at x = 2 and 10.
Y varies directly with x" means y = constant * x or y = kx ----- (1)1. when x = -1/2, y = 2Put it in (1):2 = k * (-1/2)multiply by 2:4 = k * (-1)4 = -kk = -4y = -4x
"find the value of y when x= -0.3"y = -4x = (-4) * (-0.3) = 1.2
So for each problem, start with y = kxThey give you one x and one y value.Put it in y = kx and find k.Then put x = -0.3 and find y.

Answer:
x=7.31
Step-by-step explanation:
There are two x's, so they represent the equation 2x=14.62. If we solve for x, we have to divide each side by 2:
2x/2=14.62/2.
If we divide, we get x=7.31
You would have to multiply 0.500(0.5) to 45 and you would get 22.5
