Answer:  B) y = 2 · 3ˣ

<u>Step-by-step explanation:</u>

We can see that (2, 18) is a point on the graph.

Plug it into the equations to see which one make a true statement.

        A) y = 1 · 3ˣ

            18 = 1 · 3²

            18 = 1 · 9

             18 ≠ 9

       B) y = 2 · 3ˣ

          18 = 2 · 3²

           18 = 2 · 9

           18 = 18             This works!

       C) y = 3 · 2ˣ

          18 = 3 · 2²

           18 = 3 · 4

           18 ≠ 12

       D) y = 4 · 3ˣ

          18 = 4 · 3²

           18 = 4 · 9

           18 ≠ 36

Please do this for me <br><br> I am very lazy
Alexandra [31]

First, let's turn all the numbers into improper fractions so that we can find the answer easier.

-2 \frac{1}{4} = r - \frac{4}{5}

-\frac{9}{4} = r - \frac{4}{5}

Now we have to isolate 'r'.

First, we have to make sure that the variable is on one side and all the numbers are on the other side.

To do this, we have to add \frac{4}{5} to both sides.

In order to do this, we need to ensure that both fractions have a common denominator.

-\frac{9}{4} = r - \frac{4}{5}

Ensure that the denominators are the same:

\frac{45}{20} = r - \frac{16}{20}

\frac{45}{20} + \frac{16}{20} = r

\frac{61}{20} = r

Good luck!

Line / is shown on the graph below. If another line is drawn, perpendicular to line I, what must be its slope?
juin [17]

Answer:

Undefined

Step-by-step explanation:

The slope on the graph is horizontal so there's no slope and the answer is just y = 3

For a line to be perpendicular to a horizontal line, it is going to be a vertical line.

All vertical lines have an undefined slope.

Solve for p: -9 + p &lt; 15 <br> A. p &gt; 24 B. -p &gt; 6 C. p &lt; 24 D. -p &lt; -6
Soloha48 [4]

Answer:

C.  In the given expression -9 + p < 15 , the value of p <  24.

Step-by-step explanation:

Here, the given expression is :

-9 + p < 15

Now, solving for the value of p.

If equals are added to both sides of inequality, the inequality remains unchanged.

Now, -9 + p < 15

⇒  -9 + p  + 9 < 15  + 9                                  (adding +9 on both sides)

or,  p <  24

Hence, in the given expression -9 + p < 15  the value of  p <  24.
