To solve for x, we have to remember to isolate the variable.

For 1/2, we can make that 0.5, since their values are equivalent. Our equation:

Let's distribute the 0.5 first.


Now, let's simplify the right side of the equation. We have to distribute the negative to 3x and 1.

Then, we simplify the entire expression.


Our equation now:

Let's add 3x to the right and 3x to the left to simplify the -3x on the right side of the equation.


Let's do the same thing we did in Step 3 to 1.5. Subtract 1.5 on both sides of the equation.


Finally, we divide both sides by 6 to isolate x.

Determine if the function is quadratic

Start by representing the function as an x-y table
x:- 5 || 7 || 9 || 11
y:- 7 || 11 || 14 || 18
Next; Calculate the difference between the values of y



<em>The resulting difference are: 4 || 3 || 4</em>
Next; Calculate the difference between the difference of values of y


<em>The resulting difference are: -1 || 1</em>
<em>For the function to be quadratic, the above difference must be the same and since they are not, then the function does not represent a quadratic function.</em>
<em>Option D answers the question</em>
