Answer:
You would have to make and sell 600 video games.
Step-by-step explanation:
Step 1: Subtract the total cost of a game from the sell value to get the overall income from each game.
$20 - $2.65 = $17.35
Step 2: Divide the investment price in equipment by the overall income from each game.
$10,410 ÷ $17.35 = 600
Therefore, you would need to make and sell 600 video games before your business breaks even.
Answer:
4. 11
5. -11
6. ± 5
Step-by-step explanation:
4. (g - h)(x) = x² - 1 - ( -2x +3) = x² - 1 + 2x -3 = x² +2x -4
(g - h)(3) = 3² + 2.3 - 4 = 9 + 6 - 4 = 11
5. (h-g)(x) = -2x + 3 - (x² - 1) = -2x + 3 - x² + 1 = -x² - 2x + 4
(h-g)(3) = -3² - 2(3) + 4 = -9 -6 +4 = -11
6. g(x) = 24
24 = x² - 1
x² = 24 + 1 = 25
x = √25 = ± 5
