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.
Answer:
Step-by-step explanation:
The simple way of calculating a perimeter is to add all of the sides.
For a rectangle this would equal 2 x length + 2 x width
P = 2(6x + 3) + 2(-2x - 5)
= 12x + 6 - 4x - 10
= 8x - 4
At a higher level both the length and width must be greater than zero (= zero is a trivial rectangle)
6x + 3 > 0
6x > -3
x > -0.5
-2x - 5 > 0
2x + 5 < 0 (multiplying by -1 reverses the inequality)
2x < -5
x < -2.5
This rectangle cannot exist as x cannot be < -2.5 and > -0.5 at the same time!
Answer is the third one. It is the only answer where all points work in the equation.
