9 − 3 = 4 − 3
5 − 3 = −3
5 = 0
= 0
Hope this helps you ! :)

Other method:

zeros of numerator and denominator are x = -2 and x = 4.
Look at the second picture.
for x < -2 → x + 2 < 0 and x - 4 < 0
therefore 
for -2 < x < 4 → x + 2 > 0 and x - 4 < 0
therefore 
for x > 4 → x + 2 > 0 and x - 4 > 0
therefore 
<h3>Answer: B) -2 < x < 4</h3>
Answer:
12,500 units
Step-by-step explanation:
Given:
Selling cost of the pump = $10
Variable cost of producing each unit = 60% of selling cost
or
Variable cost of producing each unit = 0.60 × $10 = $6
Monthly fixed cost = $50,000
Now,
The profit per unit = Selling cost - Variable cost
or
The profit per unit = $10 - $6 = $4
Therefore,
The breakeven point =
or
the breakeven point =
or
the breakeven point = 12,500 units
Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate.
Answer:
4
Step-by-step explanation:
ΔABC is congruent with ΔDEF. That means the corresponding sides are congruent.
Look at the order of the letters. EF are the last two letters of ΔDEF. So this corresponds with the last two letters of ΔABC. Therefore, EF ≅ BC.
EF ≅ BC
x² + 8x = 48
x² + 8x − 48 = 0
(x + 12) (x − 4) = 0
x = -12 or 4
Since x can't be negative, x = 4.
