Yes it means the line crosses the x-axis at the value of zero.
If it is a parabola, then it means the vertex of the parabola lies on the x-axis.

Answer:

$3x^{2} -3x+8-\frac{9}{x+1}$

Step-by-step explanation:

Since we're dividing the polynomial by $(x+1)$ , we'll be using -1 to start the division.

Before setting the division up, let's list the coefficients of $x$ from descending powers and the constant.

The coefficient of $x^{3}$ is 3

Since we don't see an $x^{2}$ , the coefficient will be 0.

The coefficient of $x$ is 5.

Lastly, the constant, which is the term without the $x$ is -1.

Refer to the attached picture before continuing.

After referring to the picture, we now have the coefficients for the quotient.

The coefficient of $x^{2}$ is 3.

The coefficient of $x$ is -3.

The constant is 8.

Lastly, since the last number is not zero, it's the remainder just like regular division. This can be tricky to remember, but -9 is not the actual remainder.

The remainder is actually $\frac{-9}{x+1}$ .

Now putting all the pieces together, we get:

$3x^{2} -3x+8-\frac{9}{x+1}$

Out of 120 high school boys and 80 high school girls, 45 tried out for track. Of those 45, 12 were girls.

<span>So there are 33 boys who tried out for track. And this is 27.5 % of the total boys. And there 15% of the girls who tried out for the track. And in total 22.5 % of the total population tried out for track</span>

The correct answer is D.

This is because a converse statement switches the places of the hypothesis and conclusion.
