Which numbers are rational?

Answers

Answer 1

Answer:

1, 4, 5

Step-by-step explanation:

a rational number is defined as a number that can be written as a fraction. so, 4 and 5 are automatically checked off. 1 also simplifies to plus or minus 11, which is a whole number, meaning it is automatically rational. 2 is not rational because there is no set pattern in the decimal, so it can not be written as a fraction. 3 is the same thing, so it is irrational.

1/3 (b+6)=1/4b +8

Answers

Answer:
b=72

Explanation:
1/3(b+6)=1/4b+8
Distribute 1/3 into the parentheses
1/3b+2=1/4b+8
Move like terms to either side
1/3b-1/4b=8-2
1/12b=6
Divide both sides by 1/12 to isolate b
b=6/ 1/12
Dividing a fraction is the same thing as multiplying its flip
b=6(12)
b=72

Group of answer choices

{(2, -1), (4, -2), (6, -3), (8, -4)}

{(1, -5), (1, 5), (2, -10), (2, -15)}

{(3, 3), (3, 4), (4, 3), (4, 4)}

Answers

Answer: Choice B

{(2, -1), (4, -2), (6, -3), (8, -4)}

In this relation, each point has a unique x coordinate. None of the x coordinates repeat themselves.

For something like choice A, we have x = 1 repeated. The input x = 1 leads to multiple outputs (y = 1 and y = 0 simultaneously).

The same situation happens in choice C also. This time x = 1 and x = 2 repeat themselves.

Choice D has x = 3 and x = 4 repeat themselves.

A function is only possible if each x input leads to exactly one y output.

The additive inverse of -7

Answers

Answer:

Step-by-step explanation:

An "additive inverse" refers to a number that when added to a specific number equals to "zero."

In the question above, the additive inverse of -7 is 7 because: -7 + 7 = 0

Other examples:

1. The additive inverse of 2 is -2 because: 2 + (-2) = 0

2. The additive inverse of -100 is 100 because: -100 + 100 = 0

3. The additive inverse of [tex]\frac{1}{2}[/tex] is -[tex]\frac{1}{2}[/tex] because: [tex]\frac{1}{2}[/tex] + -[tex]\frac{1}{2}[/tex] = 0

The additive inverse of -7 is equal to 7.

The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.

To determine the additive inverse of -7, we need to find the number that, when added to -7, results in zero.

To do this, we can multiply -7 by -1, which is the multiplicative inverse of 1. Multiplying a number by its multiplicative inverse always gives the additive inverse of that number.

So, -7 multiplied by -1 is:

-7 x -1 = 7

Therefore, the additive inverse of -7 is 7.

Solve the inequality 2x-8 ≤ 14 and graph its solutions on the number line.

Answers

Answer:

Step-by-step explanation:

2x-8 ≤ 14

1. Add 8 to both sides of the inequality sign to move the 8 from the left side to the right side.

2x ≤ 22

2. Divide both sides by 2 to get the x alone.

x ≤ 11

3. Make a number line from 8 to 13 (numbers can be changed), draw a circle above the number 11 and fill in the circle.

4. Now, make a line going from the circle to the left and draw an arrow at the end.

There ya gooooo :)

The value of the expression √48 will be given as 6.93.

What is the value of the expression?

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The expression is given below.

⇒ √48

The power of the number 48 is 1/2. Then the value of the expression will be

[tex]\rightarrow \left ( 48 \right )^{\frac{1}{2}}\\[/tex]
