A laptop computer is purchased for $2450. After each year, the resale value decreases by 30%. What will the resale value be after 3 years? Use the calculator provided and found your answer to the nearest dollar.

$840

Step-by-step explanation:

This is an example of a compound percentage change.

To work this out you should multiply $2450 by 0.70 to the power of 3.

You would multiply by 0.70 as you are decreasing the amount by 30%. And so by multiplying the amount by 0.70 you are decreasing it by 30% and by doing it to the power of 3 you are decreasing it 3 times.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
