F(x) = 6 + x
6 is a one time admission fee. Each ride would cost $1, so you would just add 1 into the admission fee to see what you paid total.

The graph below represents an employee's earnings based on units sold. What can be interpreted from the slope of this graph?

Vesna [10]

Answer:

A

Step-by-step explanation:

<u />

From inspection of the graph, we can see that every time the x-value increases by 10, the y-value increases by 1000.

So, the employee earns an additional $1000 for every 10 units sold.

To calculate how much the employee earns for every 1 unit sold, divide $1000 by 10:

1000 ÷ 10 = 100

Therefore, the employee earns an additional $100 for every one unit sold.

<u />

<u>Proof</u>

This can be proved by calculating the slope (gradient) of the graph:

$\sf slope=\dfrac{y_2-y_1}{x_2-x_1}$

where $\sf (x_1,y_1)$ and $\sf (x_2,y_2)$ are two points on the line

When picking the two points, remember that the <u>y-values are in </u><u><em>thousands</em></u><u> </u><u>of dollars.</u>

<u />

Two points on the line:

(0, 30000) and (20, 32000)

Substituting these into the formula:

$\sf \implies slope=\dfrac{32000-30000}{20-0}=\dfrac{2000}{20}=100$

Therefore, the employee earns an additional $100 for every one unit sold.

65% of students in your school participate in at least one after school activity. If there are 980 students in you school, how m

aniked [119]

100% - 65% = 35% of students DO NOT participate

980 * 35/100 = 980 * 0.35 = 343 students don't participate

given that the center of a circle is at point (-3,5) and that the radius of the circle is 6 units, write the the equation of the

Anika [276]

The equation of a cricle is
$(x-h)^{2}+(y-k)^{2}=r^{2}$
h being the x coordinate of the given point and k being the y coordinate of the given point (r also being the radius).

Now we have to plug the points into the equation
$(x--3)^{2} +(y-5)^{2} = 6^{2}$
now just simplify the the equation
$(x+3)^{2} +(y-5)^{2} = 36$
