What are the amplitude and midline? Amplitude: 2; midline: y = 3
Amplitude: 1; midline: y = 3
Amplitude: 2; midline: y = 1
Amplitude: 3; midline: y = 2

Amplitude 3; midline y=2

Step-by-step explanation:

The midline is the mean of both ends of the function in the graph.

The amplitude is the vertical distance between the midline and one of the end points.

(sorry for the basic math, i just want to make sure you know where im getting the values from)

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
