A plumber chargers $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost,

daser333 [38]

25$ is the flat fee. 50$ is the amount charged per hour. Therefore the equation is C=25+50h where c is the total cost and h is the amount of hours.

C=25+50h

To find the amount of money for 8 hours simply plug in 8 for h and you get 400. Don't forget to add the flat fee of 25. The total cost for 8 hours of service is 425.

To find the amount of money for 10 hours of work, plug in 10 for h and you get 500. Add 25 to 500 and you get 525 for a total of 10 hours of work.

Hope this helped...

How many feet are in 13 miles, 176 yards? Enter only the number. Do not include units.

hammer [34]

Answer:

69,168

Step-by-step explanation:

1 mile = 5280 ft

13 miles · 5280 ft = 68,640 ft

1 yd = 3 ft

176 yds · 3 ft = 528 ft

68640 ft + 528 ft = 69,168 ft

Multiply each equation by a constant that would help to eliminate the y terms.

Zinaida [17]

Answer:

Therefore the required resulting equation is

$6x-15y=-63\\-15x+15y=90$

6 x minus 15 y = negative 63.

Negative 15 x + 15 y = 90

Step-by-step explanation:

Given:

$2x-5y=-21$ ......................Equation ( 1 )

$3x-3y=-18$ ......................Equation ( 2 )

To Find:

Expression after multiplying to eliminate y term,

Solution:

So to eliminate 'y' term we need to multiply equation 1 by a constant 3 and equation 2 by a constant -5, such that equations becomes

$3(2x-5y)=3\times -21\\\\6x-15y=-63$ .....( 1 )

$-5(3x-3y)=-5\times -18\\\\-15x+15y=90$ .....( 2 )

so now by adding new equation one and two we can eliminate y term that means -15y and +15y will get cancel,

Therefore the required resulting equation is

$6x-15y=-63\\-15x+15y=90$

6 x minus 15 y = negative 63.

Negative 15 x + 15 y = 90

Select the correct word to describe the function. the equation y = startfraction 5 x cubed over 8 endfraction represents functio

balandron [24]

The functions and their descriptions are:

Polynomial: $y = \frac{5x^3}{8}$ and $y = 5x^3 + 8$
Logarithm: $y = 6 + 0.25\ln(x)$
Exponential $y = \frac{18}{1 + 6e^{-0.25x}}$

<h3>How to describe the functions?</h3>

The functions are given as:

$y = \frac{5x^3}{8}$

$y = 6 + 0.25\ln(x)$

$y = \frac{18}{1 + 6e^{-0.25x}}$

$y = 5x^3 + 8$

The functions would be described based on the type of function they represent.

Functions that use the "ln" keyword are logarithmic functions, while functions that use the "e" keyword are exponential functions.
