Identify the domain of the function shown in the graph.
Leno4ka [110]

Domain is set of all x-values. You are supposed to focus on the x-axis instead.

From the graph, the point starts from x = -5 and ends on x = 5. That means no values would exist after x = 5 or before x = -5.

Hence, the domain starts from -5 to 5.

Answer

  • -5≤x≤5

Simplify y^-3 <br><br> a.3/y<br> b.1/y^3<br> c.-3y<br> d.-1/y^3
nignag [31]

Answer:

b. \frac{1}{y^3}

Step-by-step explanation:

Here we are given  y^{-3} and are asked to simplify it. We are going to apply the law of exponents which says that

a^{-n}=\frac{1}{a^n}

Hence applying this rule in our problem we get, where a=y and n=3

y^{-3}=\frac{1}{y^3}

Hence our C) Option is correct

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was
alekssr [168]
The formula would be set up as ratios (or fractions). The first ratio is 6:5, which in total is 11. There were 6 yes out of 11, so the fraction = 6/11.

The second fraction has a total of 5918, however you do not know the amount of yes votes, so the variable placeholder will be called "x".

The final formula would be:
 6/11 = x/5918

 You do cross multiplication and you get:
11x = 35508. You divide both sides, and you get x = 3228.

Because x is the placeholder for the amount of yes votes, and x = 3228, the amount of yes votes is 3228

stealth61 [152]

Answer:

Gross profit formula= 3x

x= number of units sold

Step-by-step explanation:

Giving the following information:

Unitary variable cost= $2

Selling price per unit= $5

<u>To calculate the profit earned, we need to use the unitary contribution margin formula</u>. The contribution margin is a product's price minus all associated variable costs (sales- variable costs), resulting in the incremental profit earned for each unit sold.

Unitary contribution margin= 5 - 2 = 3

<u>Now, the profit formula:</u>

Gross profit formula= number of units*unitary contribution margin

Gross profit formula= 3x

x= number of units sold
