If (3,2) is an ordered pair of the function f(x),which of the following must be an ordered pair of the inverse of f(x)

Answers

Answer 1

Answer:

Answer:

B. (2,3)

Step-by-step explanation:

If the point $(x,y)$ lies on the graph of an invertible function, then the point, $(y,x)$ must lie on its inverse.

If (3,2) is an ordered pair of $f(x)$ , then $(2,3)$ must be an ordered pair of $f^(-1)(x)$

The correct choice is B.

Answer 2

Answer:

Answer:

Choice B is correct.

Step-by-step explanation:

We have given the ordered pair of function:

(3,2).

We have to find the ordered pair to inverse of f(x).

If (x,y) is the ordered pair of f(x) then (y,x) is the ordered pair of the inverse of f(x).

The domain of function is the range of its inverse same is the case with the range.

So, the inverse function has (2,3) ordered pair.

Choice B is correct.

What s an equivalent fraction to 70/80

Answers

An equivalent fraction is a fraction where its numerator and denominator are multiplied by the same constant factor. If the fraction can be simplified more, then the equivalent fraction simplified is also an equivalent fraction.

Some equivalent fractions for $(70)/(80)$ are $(7)/(8) , (140)/(160) , (14)/(16) , (210)/(240) , (21)/(24), ...$ and so on.

Hope that helps :)

What is PEMDAS?

The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.

Given:

We have an expression,

3 × (3 + 12 ÷ 3) - 4.

In order to solve the problem,

we can use PEMDAS.

First, we solve parenthesis,

and division.

3 × (3 + 4) - 4.

Now,

3 × 7 - 4.

Now, multiplication,

21 - 4.

= 17

Therefore, the solution is 17.

By the order of operations, division takes place before addition. So, (3+12/3) is not equal to (3+12)/3. He should have gotten 3+12/3=3+4=7.

What is (-0.75x + 6) -(2.5x -1.9)

Answers

The solution to the expression (-0.75x + 6) -(2.5x -1.9) is -3.25x + 7.9

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

(-0.75x + 6) -(2.5x -1.9)

Open teh brackets

So, we have

(-0.75x + 6) -(2.5x -1.9) = -0.75x + 6 -2.5x + 1.9

Evaluate the like terms

So, we have

(-0.75x + 6) -(2.5x -1.9) = -3.25x + 7.9

Hence, the solution is -3.25x + 7.9
