You break even if you spend exactly as much as you gain. In other words, if the cost and the revenue are the same:
Subtract 0.25 from both sides:
Divide both sides by 1.25:
So, they must sell 116 computers to break even. If they sell less, they'll lose money. If they sell more, they'll start making profit.
Answer:
Step-by-step explanation:
i) 1
ii) see attached
iii) as x goes from 0 to 2, y decreases parabolically from 1 to an acme at -3
iv) y = (x - 2)² - 3
v) -3 < t < 1
if t < -3 no intersection occurs between y = t and y = (x - 2)² - 3
if t = -3, y = t intersects the curve at only one point, (2, -3)
if -3 < t < 1 there exist two intersecting points with positive x values
if t = 1 there exist only one positive x value intersection as the other is at (0, 1) and 0 is neither positive nor negative.
if t > 1 there is one positive x value intersection and one negative x value intersection.
