Answer:
200 units
Step-by-step explanation:
The total income must be at least equal to the costs, and that is:
10*U = 5*U + 1000 Solving for U, which is the amount of units sold per month:
U = 1000/5 = 200 units.
The x intercepts must be 1 and -4, so C.
Answer:
The integers are 4 and 7 or -2 and 1.
Step-by-step explanation:
You can make a system of equations with the description of the two integers.
1. x = y + 3
2. 2x + 2 = y^2
The simplest and the fastest way to solve this system in this case is substitution. You can substitute x for y + 3 in the second equation.
1. x = y + 3
2. 2(y + 3) + 2 = y^2
Now simplify and solve the second one. For convenience, I will just disregard the first equation for now.
2y + 6 + 2 = y^2
y^2 - 2y - 8 = 0
You can factor this equation to solve for y.
(y - 4) (y + 2) = 0
y = 4, y = -2
Now we can substitute the value of y for x in the first equation.
x = 7, x = 1
The answer is B u put them all in a fraction and put them in simpliest form and all the answers in B come up to 7 over 8
