Answer:
b = 43
Step-by-step explanation:
So let's plug things in first:
y= 2x - 20 and y= -5x +b which can become →
2x - 20 = -5x + b (now you said that x=9 so let's plug that in)
2(9) -20 = -5(9) + b (now try solving that)
18 -20 = -45 + b → -2 = -45 + b ( so then add 45 to both sides)
43 = b ( and there's your answer )
(5x - 2)²
Step-by-step explanation:
25x² - 20 + 4
(5x - 2)(5x - 2)
(5x - 2)²
Answer:
Step-by-step explanation:
Given the weekly revenue and cost function
R(d) = 12000
C (d) = 350d + 5000
A firm break even point occurs when the amount of revenue is equal to the cost.
If the company Bridal solution breaks even then C(d) = R(d)
350d + 5000 = 12000
350d = 12000 - 5000
350d = 7000
divide both sides by 350
350d/350 = 7000/350
d = 20
Hence the total number of wedding dressing to be sold by Bridal Solutions for them to break even is 20 dresses.
