The function C(x) = 25.50x + 50 models the total cost for a cleaning company to clean a house, where x is the number of hours it
vodomira [7]

Answer:

<em>The average rate of change is $25.5 per hour, option B.</em>

Step-by-step explanation:

<u>Average Rate of Change </u>

When we are explicitly given some function C(x), we sometimes need to know the rate of change of C when x goes from x=x_1 to x=x_2. It can be computed as the slope of a line .

\displaystyle m=\frac{C(x_2)-C(x_1)}{x_2-x_1}

The provided function is

C(x)=25.50x + 50

We are required to compute the average rate of change between the points

x_1=3\ ,\ x_2=9

Let's compute

C(3)=25.50(3) + 50=126.5

C(9)=25.50(9) + 50=279.5

\displaystyle m=\frac{279.5-126.5}{9-3}

\displaystyle m=\frac{153}{6}=25.5

The average rate of change is $25.5 per hour, option B.

Determine is the solution set for the system of equations shown is the empty set contains one point or is infinite X+2y=0; 2x+4y
Sedaia [141]
We can use elimination to solve the system:

x+2y=0           Multiply the first equation by negative 2 so we can eliminate
2x+4y=0

-2-4y=0         Add them, -2X+2X= 0, -4Y+4Y= 0
2x+4y=0                   

0=0 

Since 0 is indeed equal to 0 you have INFINITELY MANY SOLUTIONS.

you could also put both equation in slope intercept form and see if the slopes and Y-intercept are the same.

Please help me lol the struggle is real
s344n2d4d5 [400]
<span> You can find the circumference of a circle just by multiplying the diameter by pi. Plugging π into your calculator will give you its numerical value, which is a closer approximation of 3.14 or 22/7. Plug the given value of the diameter into the formula and solve.</span>
