Answer with explanation:

Annual Salary of Mindy = $ 24, 590

Monthly Salary of Mindy $=\frac{24590}{12}$

We will use $\frac{28}{36}$ rule to find the maximum monthly rent that, Mindy can afford.

This rule states that, 28% of your monthly gross income should be used for Housing finances and 36% of your monthly gross income should be used for Debt Purposes.

So, Maximum Monthly rent that Mindy can afford

$=28 \text{percent of}} \frac{24590}{12}\\\\=\frac{28}{100} \times \frac{24590}{12}\\\\=\frac{28 \times 24590}{1200}\\\\=\frac{688520}{1200}\\\\=573.7666$

= 573.77 (approx)

For which function is f(x) equal to f^1(x) ( answer choices in picture )

Sonja [21]

Answer:

C. $f(x)=\frac{x+1}{x-1}$

Step-by-step explanation:

Let's find the inverse of each of the given options.

Option A:

$f(x)=\frac{x+6}{x-6}\\y=\frac{x+6}{x-6}$

To find $f^{-1}(x)$ , replace 'x' with 'y' and 'y' with 'x'. This gives,

$x=\frac{y+6}{y-6}$

Rewrite in terms of 'y'. This gives,

$x(y-6)=y+6\\xy-6x=y+6\\xy-y=6x+6\\y=\frac{6x+6}{x-1}$

The given function $y=\frac{6x+6}{x-1}\ne y=\frac{x+6}{x-6}$

So, option A is incorrect.

Option B:

$f(x)=\frac{x+2}{x-2}\\y=\frac{x+2}{x-2}$

To find $f^{-1}(x)$ , replace 'x' with 'y' and 'y' with 'x'. This gives,

$x=\frac{y+2}{y-2}$

Rewrite in terms of 'y'. This gives,

$x(y-2)=y+2\\xy-2x=y+2\\xy-y=2x+2\\y=\frac{2x+2}{x-1}$

The given function $y=\frac{2x+2}{x-1}\ne y=\frac{x+2}{x-2}$

So, option B is incorrect.

Option C:

$f(x)=\frac{x+1}{x-1}\\y=\frac{x+1}{x-1}$

To find $f^{-1}(x)$ , replace 'x' with 'y' and 'y' with 'x'. This gives,

$x=\frac{y+1}{y-1}$

Rewrite in terms of 'y'. This gives,

$x(y-1)=y+1\\xy-x=y+1\\xy-y=x+1\\y=\frac{x+1}{x-1}$

The given function $y=\frac{x+1}{x-1}\ equals\ y=\frac{x+1}{x-1}$

So, option C is correct.

Option D:

$f(x)=\frac{x+5}{x-5}\\y=\frac{x+5}{x-5}$

To find $f^{-1}(x)$ , replace 'x' with 'y' and 'y' with 'x'. This gives,

$x=\frac{y+5}{y-5}$

Rewrite in terms of 'y'. This gives,

$x(y-5)=y+5\\xy-5x=y+5\\xy-y=5x+5\\y=\frac{5x+5}{x-1}$

The given function $y=\frac{5x+5}{x-1}\ne y=\frac{x+6}{x-6}$

So, option D is incorrect.

Therefore, only option C is correct.

Tyler works in retail where she earns $10.50 per hour. She also earns $15 for every new credit account she gets customers to ope

Hitman42 [59]

A
coefficient = 10.50 or 15, both real numbers that qualify variables
variable = c and h
constant = 50

B
10.50h + 15c + 50
10.5 x 37 + 15 x 12 + 50
388.50 + 180 + 50 = 618.50

C
Coefficient would change from 10.50 to 11.25
<span>It is fixed until the next raise.

I hope my answer has come to your help. God bless and have a nice day ahead!</span>

The inequality which represents the missing dimension x is x≥1.6 or x≥8 / 5.

Given that the area is greater than or equal to 8 square feet and image is attached below.

We want to find the missing inequality x in the form of inequality.

The figure is assumed to be a right triangle with Root = x and perpendicular = 10ft.

As we know the area of a triangle is half the product of the base and the height.

First of all, we will find the area of the triangle by substituting the given values we get

Area=(1/2)×Base×height

Area=(1/2)×x×10

Area=5x ......(1)

Assume that this area is greater than or equal to 8 square feet.

That means Area≥8ft² ......(2)

Now we will balance equation (1) and equation (2), we get

5x≥8ft²

Furthermore, they we will divide both sides by 5 we get

(5x)/5≥8/5

x≥8/5

x≥1.6

Therefore, the inequality represents the missing size x when the area is larger or equal to 8 square feet is x ≥1.6ft².

What is 12x − y = 10 in slope form equation?

DochEvi [55]

Y=12x-10

Explanation:

You basically what to get y by itself so-

12x-y=10

You will add y to both sides

12x=y+10

Then subtract ten from both sides

12x-10=y or y=12x-10
