(2x^2 + 4x + 6) - (-3x - 5x^2 + 4)

The negative sign separating the expressions is just multiplying the rightmost expression by -1.

(2x^2 + 4x + 6) + (3x + 5x^2 - 4)

Now, let's add together terms that share the same variable.

2x^2 + 5x^2 = 7x^2

4x + 3x = 7x

6 + (-4) = 2

Let's combine each of these terms into one expression.

7x^2 + 7x + 2 is the final answer.

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

Which is greater? X + -6 or X + -2<br>​
irina1246 [14]
X is just a place holder so it really depends if you know what x is but for right now let’s say it’s 0
Ok so -6 is less than -2 so the larger the negative number is the less it is if that makes sense so the greater number is -2
So x+-2 is greater
