Answer:

The inverse is ±sqrt(100-x)

Step-by-step explanation:

To find the inverse, exchange x and y

x = 100 -y^2

Solve for y

Subtract 100 from each side

x - 100 = -y^2

Divide by -1

-x +100 = y^2

Take the square root of each side

±sqrt(100-x) = sqrt(y^2)

±sqrt(100-x) =y

The inverse is ±sqrt(100-x)

An airline charges an extra fee if a carry-on bag weighs more than 30 pounds. After packing, Lorrie’s carry-on weighs 21.2 pound

Goryan [66]

To solve this you subtract 21.2 from 30.
30 - 21.2 = 8.8.

If she goes over 8.8, her bag will weigh more than 30 pounds. So the answer is: no more than 8.8 pounds.
