F (x) = f (-16)
So you should plug -16 in for x 

f (-16) = 2(-16) -16

f(x) = -32 -16

f(x) = -48

Find the slope for -8y=2x+5
Anastasy [175]

Answer:

-1/4

Step-by-step explanation:

in y=mx+b, m represents the slope. Let's try to get your equation to look like that. We can see that on the left side, the y is not yet alone so we must try to accomplish that. to do that we divide by -8 from the -8y, but we must also do that to the other side. you would get y=-2/8x-5/8. then we would simplify the -2/8x into -1/4x. Now it is y=-1/4x-5/8 and that resembles y=mx+b. m is slope and -1/4 is m.

Candy bars are sold in a local store for 60 cents each. The factory has 1000 in fixed costs plus 10 cents additional expense for
pochemuha

Answer:

2000 candy bars sold

$1200 in revenue

Step-by-step explanation:

Terms we need to know:

<u>Cost</u> "C": money needed/used to make the product (factory cost and candy bar expenses)

<u>Revenue</u> "R": money earned from selling the product (candy bars sold in a local store)

<u>Profit</u> "P": money left over after revenue is used to pay costs

<u>Break-even point</u> : when there is no profit (the profit is 0), what is the total revenue and number of items sold?

Create equations for the question:

State your variables.

let 'c' be the number of candy bars sold

R(c) = 0.6c                    Candy bars sell for 60 cents each

C(c) = 0.1c + 1000          10 cents expense per candy bar and factory cost

P(c) = 0          When profit is 0, we are looking to break even

Profit = Revenue - Cost

P(c) = R(c) - C(c)             Substitute the expressions above

P(c) = 0.6c - (0.1c + 1000)

Simplify this equation first. Use the rule for subtracting binomials, where you change the positive/negative for each number inside the brackets.

P(c) = 0.6c - (0.1c + 1000)    Positive in brackets, negative when taken out

P(c) = 0.6c - 0.1c - 1000             Combine like terms

P(c) = 0.5c - 1000            General equation for this problem

0 = 0.5c - 1000                 Remember profit should be 0

<u>Isolate "c"</u> to find how many candy bars made will result in the break-even point.

0 + 1000 = 0.5c - 1000 + 1000        Add 1000 to both sides

1000 = 0.5c

1000/0.5 = 0.5c/0.5             Divide both sides by 0.5

2000 = c          Answer

c = 2000       Variable on left side for standard formatting

Now to find the revenue at the break-even point.

Go back to the revenue equation for this question. Substitute when "c" is 2000.

R(c) = 0.6c

R(2000) = 0.6(2000)        Multiply

R(2000) = 1200              Revenue at break even point

Therefore the break-even point is when 2000 candy bars are sold, which would provide $1200 in revenue.
