Graph the function on your own paper. Answer the qustions in the box below.

Yuri [45]

Answer:

$(0,0)$ is the y-interecption.

Step-by-step explanation:

The given function is

$A(x)=x^{2} -2x$

The y-intercept is found when $x=0$ , so

$A(0)=0^{2}-2(0)=0$

Therefore, the y-intercept is at the origin $(0,0)$

In the image attached you can observe the y-interception.

Additionally, the x-interceptions are at $(0,0)$ and $(2,0)$ . And the vertex of the function is at $(1,-1)$ .

Together, Raquel and Miray can spread the mulch through the yard in 2 hours. Raquel would take 0.8 times as many hours as Miray

melisa1 [442]

Using the together rate, it is found that it would take Miray 4.5 hours to spread the mulch alone.

<h3>What is the together rate?</h3>

The together rate is the <u>sum of each separate rate</u>.

For this problem, the rates are given as follows:

Together: 1/2.

Miray: 1/x, in which x is the time it would take her to spread the mulch alone.

Raquel: 1/0.8x.

Hence, applying the together rate, we have that:

$\frac{1}{x} + \frac{1}{0.8x} = \frac{1}{2}$

$\frac{1 + 1.25}{x} = \frac{1}{2}$

$\frac{2.25}{x} = \frac{1}{2}$

Applying cross multiplication:

x = 2 x 2.25

x = 4.5.

It would take Miray 4.5 hours to spread the mulch alone.
