An actor gained 20 pounds for a part and then loses 15 pounds during the filming of the movie to go along with the story describ
Tom [10]

We are given statement " gained 20 pounds and loses 15 pounds".

<em>Note: We take plus or positive sign for gain word and we take minus or negative sign for the loses word.</em>

Gained 20 means +20.

Loses 15 mean -15.

Therefore, we can setup an expression as:

<h3>+20 -15.</h3>

20 is a positive number and 15 is a negative number.

Because we have opposite signs of numbers, we would subtract them.

20-15 = 5 pounds.

The cost of using 19 HCF of water is $32.49

Given in the question:

The monthly cost (in dollars) of the water use (in dollars) is a linear function of the amount of water used (in hundreds of cubic feet, HCF)

The cost for using 17 HCF of water is using $32.13

and, the cost of using 35 HCF is $61.83.

To find the cost of using 19 HCF of water.

Now, According to the question:

The cost for using 17 HCF of water is  $32.13

and, the cost of using 35 HCF is $61.83.

To find the slope:

(17, 32.13) and (35, 61.83)

Slope = (61.83 - 32.13)/ (35 - 17) = 1.65

We know that:

Formula of slope :

y = mx + b

32.13 = 1.65 x 17 + b

b = 1.14

The equation will be :

C(x) = 1.65x + 1.14

Now, To find the cost of using 19 HCF of water.

C(19) = 1.65 × 19  + 1.14

C(19) = $32.49

Hence,  the cost of using 19 HCF of water is $32.49.

Simplify (x^3)(x^-2)
Charra [1.4K]
Hey there!

When multiplying variables with the same degree, be sure to add the two degrees being multiplied.

For example;

x * x; both of these terms have the degree of "1" as they are "x^1". Since we are multiplying them, we need to add their degrees.
x^1 * x^1 = x^2

Now that we've broken down what we are doing, let's apply this new knowledge to your problem.

(x^3)(x^-2); Remember to just add the degrees; -2 + 3 = 1
This means our product is x^1, or just x.

I hope this helps!
