as a puppy, kim's dog weighs 15 ounces. as an adult, kim's dog weighs 8 pounds. how many ounces did kim's dog gain
podryga [215]
The answer is 113 ounces.

Kim's dog weighs 8 pounds. Since 1 pound is 16 ounces, Kim's dog weighs 8 × 16 ounces = 128 ounces.
As a puppy, Kim's dog <span>weighs 15 ounces.
So, the weigh that Kim's dog gained is subtraction of 128 ounces and 15 ounces:
128 ounces - 15 ounces = 113 ounces.

</span><span>Therefore, Kim's dog gained 113 ounces.</span>

What equation is the inverse of y=2x^2-8?
Fynjy0 [20]

Step-by-step explanation:

To get the inverse, swap the x- and y-variables, then solve for y. We should have the equation: x = 2y^2 - 8

Solving for y:    

y = 2x^{2} - 8    because  y + 8 = 2x^{2} or  x =\sqrt\frac{y +  8}{2}

So on interchanging the variable, we get the equation:

x = 2y^2 - 8

x + 8 = 2y^2

y = \sqrt\frac{x + 8}{2}
