Answer:

-8

Step-by-step explanation:

-3+(-5)

When we solve the above the question we will get the answer which is equal to -8.

We have to sole the above equation by the number line

A number line consist of the negative number on the left hand side and positive numbers on right hand side which are separated by zero at equal distance .

-3+(-5)

On the number line we have to start from zero , then we have to go back 3 steps that is on the left hand side of the number line .

Now , again we have to 5 back steps on a number line and we get the our answer which is equal to -8.

Hence , the correct answer is -8.

The domain and inverse of the function

$r(x) = \frac{11}{(x - 4)^2}$ is

Domain = $\mathbb{R} - \{4\}$ ,

$r^{-1}(x) = \pm \sqrt{\frac{11}{x}} + 4$

What is a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

The given function is

$r(x) = \frac{11}{(x - 4)^2}$

r(x) is not defined if x - 4 = 0

r(x) is not defined for x = 4

Domain = $\mathbb{R} - \{4\}$ ,

Where $\mathbb{R}$ is the set of all real number

Let r(x) = y

$\frac{11}{(x-4)^2} = y\\(x - 4)^2 = \frac{11}{y}\\x - 4 = \pm \sqrt{\frac{11}{y}}\\x = \pm\sqrt{\frac{11}{y}} +4$

<em /> $r^{-1}(x) = \pm \sqrt{\frac{11}{x}} + 4$

The sales tax in Jorge's state is 7%. Jorge bought a Ford Mustang having a sales tax of $1,928.22. What was the cost of the car?

Thepotemich [5.8K]

The cost of the car is $27,546

<h3>How to calculate the cost of the car ?</h3>

The sales tax is 7%

Jorge bought a ford mustang having a sales tax of $1,928.22

Therefore the cost of the car can be calculated as follows

7/100 = 0.07

1928.22/0/07

= 27,546

Hence the cost of the car is $27,546

The third and last option. To solve the equation we take the reciprocal of 3/4 because you cannot divide fractions so it would be 15• 4/3, but flip this it could also be 15 divided by 3/4 you would just need to further simply the expression
