We know that m o n(x) = m(n(x))

This means

       (x-3) + 5 x+2
m(n(x)) =  ------------- = --------
   (x-3) -1 x-4

The domain of this function is all real numbers - {4}

The function with the same domain is h(x) = 11/x-4

Roberto is having his house painted. The job takes three days, and he pays the painter the same hourly rate

Answer:

$\$60\ per\ hour$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x -----> the number of hours worked

y ----> the amount paid in dollars

In this problem we have a proportional variation, between two variables, x, and y

Find out the constant of proportionality k

For (5,300) -----> $k=y/x$ ----> $k=300/5=60\ \$/h$

For (4,240) -----> $k=y/x$ ----> $k=240/4=60\ \$/h$

For (6,360) -----> $k=y/x$ ----> $k=360/6=60\ \$/h$

The constant k is

$k=60\ \$/h$

The equation is equal to

$y=60x$

The unit rate of change of dollars with respect to time is equal to the constant of proportionality or slope of the linear equation

therefore

$\$60\ per\ hour$

If the length of a rectangle is three times it’s width and it’s parameter is 24cm what is the area

katrin [286]

Answer:

Area = 27 cm²

Step-by-step explanation:

let L be the length of the rectangle

w the width

P the perimeter

A the area

Formulas :

P = 2×(L + w)

A = L × w

We are Given :

L = 3w

P = 2×(L + w)

⇔ 24 = 2×(3w + w)

⇔ 24 = 2×4w

⇔ 24 = 8w

⇔ w = 24/8 = 3

Then

L = 3w = 3×3 = 9

We obtain L = 9 and w = 3.

Then

A = L × w

= 9 × 3

= 27
