For this case we have the following expression:

2x ^ 2-y

We must simplify the expression for the following values:

x = 3\\y = -2

Substituting we have:2 (3) ^ 2 - (- 2) =

We have to:

- * - = +

So:

2 (3) ^ 2 - (- 2) = 2 * 9 + 2 = 18 + 2 = 20

The expression is simplified to 20.

Answer:

20

Option A

Answer: 28.35\ minutes

Step-by-step explanation:

Let be "x" the time in minutes a 150-pound person must walk at  4 mph to use at least 190 calories.

 The amount of calories that a 150-pound person uses  in 1 minute when walking at a speed of 4 mph is:

Calories\ per\ minute=6.7

Therefore, knowing this, we can write the following proportion:

\frac{1}{6.7}=\frac{x}{190}

Finally, we must solve for "x" in order to find its value.

Multiplying both sides of the equation by 190, we get this result:

(190)(\frac{1}{6.7})=(\frac{x}{190})(190)\\\\x=28.35
