Answer:
$22.5.
Step-by-step explanation:
The total revenue that is gained from the sales of the cakes is determined by multiplying the number of cakes by the price. If we let x be the number of $1 that should be deducted from the price and y be the total revenue,
y = (25 - x)(100 + 5x)
Simplifying,
y = 2500 + 25x - 5x²
We get the value of x that will give us the maximum revenue by differentiating the equation and equating the differential to zero.
dy/dx = 0 = 25 - 10x
Answer:
y=2x+b
Step-by-step explanation:
It would be 1 1/2 or 1.5 pounds in total
3/8 as a decimal is .375 (divide 3 by 8)
Then you multiply .375 by 4 then you get 1.5 or 1/ 1/2.
1) find x
y=1/(x+3) -4
y+4=1/(x+3) -4+4
y+4=1/(x+3)
x+3 =1/(y+4)
x= 1/(y+4) - 3
2) change x on y , and y on x
x= 1/(y+4) - 3
y= 1/(x+4) - 3 This is an answer.
Answer: It is the top right one.
Step-by-step explanation: That one passes the vertical line test. A function can't have any points that have the same x-coordinate.
