1. (0, 1) , (2, -9) , (3, -14) , (-6, 31)
2. The amount she pays back each week.
Answer:
-17.5
Step-by-step explanation:
-2.5 times 7
-17.5
a. Write the cost function:: C(x) = 100x + 100,000 where x is number of guitars
---------------------------------
b. Write the revenue function:: R(x) = 300x where x is number of guitars
-----------------------
c. Find the profit function.
Profit = Revenue - Cost
P(x) = R(x) - C(x)
P(x) = [ R(x) ] - [ C(x) ]
P(x) = [ 300x ] - [ 100x+100,000 ]
P(x) = 300x - 100x-100,000
P(x) = 200x - 100,000
The break even point is when the profit is 0 dollars. You don't lose any money. And you don't gain any money.
Solve 125x - 100,000 = 0
125x = 100,000
x = 800 (# of guitars made and sold)
Answer:
The slope is 2.25
The y-intercept is 3
Step-by-step explanation:
Assuming from the cut off picture, that we need to find the slope of ...
y=2.25x +3
y=mx+b form makes it easy to identify the slope and the y-intercept.
m is the slope and b is the y-intercept. Anything number that is in place of m, is the slope; and any nother in place of b is the y-intercept.
In that case, 2.25 is the slope and 3 is the y-intercept
