Answer:

After 4 months number of SUVs rented will be twice the number of compact cars rented.

Step-by-step explanation:

Tom's car rentals rented 78 SUVs and 67 compact cars.

The number of SUV's rented by Tom's Car Rentals has been increasing by 6 every month and number of compact cars are decreasing by 4.

Let after x months the number of SUVs rented will be twice of the compact cars rented.

Number of SUVs rented after x months = 78 + 6x

Number of compact cars rented after x months = 67 - 4x

78 + 6x = 2(67 - 4x)

78 + 6x = 134 - 8x

6x + 8x = 134 - 78

14x = 56

x = 4

Therefore, after 4 months number of SUVs rented will be twice the number of compact cars rented.

Explain why the vertical line test is used to determine if a graph represents a function.

Aleksandr [31]

Hi there Mary Dominguez, So what a vertical line test down is to find out if a particular graph is a function or not. What you do is take a vertical strait line and move it right to left or left to right, depending on your preference, along the X axis. The reason this works is a function can not have an x that has 2 different y values. If we use the vertical line test on a graph with say a graph that has (2,3) and (2,4) we can use the vertical line test and see that the line hits 2 points at once which means its not a function :)

What is the simplified form of the following expression? 2 StartRoot 18 EndRoot + 3 StartRoot 2 EndRoot + StartRoot 162 EndRoot

ExtremeBDS [4]

Answer:

$18\sqrt2$

Step-by-step explanation:

To simplify:

$2 \sqrt{18}+ 3 \sqrt2+ \sqrt{162 }$

First of all, let us write 18 and 162 as product of prime factors:

$18 = 2 \times \underline{3 \times 3}\\162 = 2 \times \underline{3 \times 3} \times \underline{3 \times 3}$

The pairs are underlined as above.

While taking roots, only one of the numbers from the pairs will be chosen.

Now, taking square roots.

$\sqrt{18} =3 \sqrt2$

$162 = 3 \times 3 \times \sqrt 2 = 9 \sqrt2$

So, the given expression becomes:

$2 \sqrt{18}+ 3 \sqrt2+ \sqrt{162 } = 2 \times 3\sqrt2 + 3\sqrt2 +9\sqrt2\\\Rightarrow 6\sqrt2 + 3\sqrt2 +9\sqrt2\\\Rightarrow \sqrt2(6+3+9)\\\Rightarrow \bold{18\sqrt2}$

So, the answer is:

$18\sqrt2$ or 18 StartRoot 2 EndRoot
