A60 percent increase followed by a 40 percent decrease

This winds up being a 4% decrease.

Step-by-step explanation:

For an example, we will take an object that costs $100. If we mark it up by 60%, the new cost will be $160.

Now we want to take the cost of $160, and subtract 40%. First we need to find 40% of $160. We can do that by multiplying them together.

$160*40% = $64

Now we will subtract that from the cost of the item after the increase.

$160 - $64 = $96.

Even though the percent decrease was less, the order in which we do it causes this to be an overall decrease

the nearest power is 1.651.

means 7482 to the 1.651th power is almost equal to 2489287

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=
