Which of the sets of ordered pairs represents a function? (1 point)

P = {(6, −7), (3, −2), (−9, 2), (−5, −7)}

Q = {(−7, 8), (4, −6), (−3, 1), (1, 5)}

Answers

Answer:

Conclusion:

Both sets represent the function.

Step-by-step explanation:

We know that a function relates an input to an output.

For example, a certain plant grows 10 cm each year. Thus, the height of the plant is associated with its age using the function

h (age) = age × 10

Thus, if the age of the plant is 2 years, the height is:

h(10) = 2 × 10 = 20 cm

Set P

P = {(6, −7), (3, −2), (−9, 2), (−5, −7)}

The set P represents the function because the function relates an input to an output. In other words, here each input is related to exactly one output.

The x-values are 6, 3, -9, and -5.

Thus, there are no duplicated inputs or x-values.

Therefore, the set P  of ordered pairs represents a function.

Set Q

Q = {(−7, 8), (4, −6), (−3, 1), (1, 5)}

The set P represents the function because the function relates an input to an output. In other words, here each input is related to exactly one output.

The x-values are -7, 4, -3, and 1.

Thus, there are no duplicated inputs or x-values.

Therefore, the set Q  of ordered pairs also represents a function.

Conclusion:

Both sets represent the function.

Samantha created part of a table to show her savings. She saved at the same rate each week. Which graph shows this relationship?

Answers

Answer:

The answer is B

Step-by-step explanation:

because it is going up by 6 so graph B is the only graph going up by 6.

The  correct graph is with $6, $12, $18, $24.

What is Graph?

The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.

In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.

Usually, data that varies over time is represented with a line graph.

Given:

As, from the given graph

The saving increases each week at the same rate therefore saving increases from 3rd to 4th week is 6$. this means that saving increases $6 each week.

Hence, option to is correct with $6, $12, $18, $24.

Choose the situation in which the use of approximate numbers is most appropriate.
A)

B)
ordering chairs for a kitchen table
purchasing barbeque to serve at a party
D
ordering uniforms for the high school basketbalt team

Answers

I good with D because i think it’s for Sure the right answer

Answer:

I would say that A  is your answer.

I think this because you would not need to have any specific number of trees in your yard, but you would need a specific number of things for all of your other options.

Step-by-step explanation:

You probably wouldn't approximate on how many chairs you put in a kitchen. What if you have a 5-member family and you aproxomate the chair number to 4. that would be useless so B is wrong.

C is wrong because you are only getting 1 barbaque. no approximation is nessisary for one item.

D is certainly wrong because you wouldn't want to leave out a uniform, that would mean one member of the basketball team may not get one.

A complex number has a real part 4 and an imaginary part coefficient of -3. Which binomial is equivalent to this complex number?

Answers

Answer:

4-3i

Step-by-step explanation:

Here, we want to select the option that best correlate

The real and the complex part can be represented as;

a + bi

In this case, a is the real, b is the complex

So we have that;

Real part 4 and imaginary coefficient of 3

That will be

4 -3i

Answer:b

Given that a = 3 and b = -1, what is the value of 2a - b?

Answers

Answer:

the answer is 7.

Step-by-step explanation:

here's why......if u place the 3 where a is it will become multiplication so that would be 2 times 3 minus b now but if u place -1 the minus becomes addition so it will be 6+1 which is 7.

Answer:

The value of expression when a=3 and b=-1 is 7

Step-by-step explanation:

Given expression is:

2a - b

Also given that

a = 3

b = -1

In order to find the value of the expression, we have to put 3 in place of a and -1 in place of b in the expression

So putting the values

[tex]=2(3)-(-1)\\=6+1\\=7[/tex]

Hence,

The value of expression when a=3 and b=-1 is 7

Answer:

g= - 32

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

Step 2: Flip the equation.

Step 3: Add 5 to both sides.

Step 4: Multiply both sides by 4/(-1).

g=−32

Answer:

g = -32

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

3 = g/-4 - 5

Step 2: Solve for g

Add 5 to both sides:                    8 = g/-4Multiply -4 on both sides:            -32 = gRewrite:                                        g = -32

Step 3: Check

Plug in g into the original equation to verify it's a solution.

Substitute in g:                    3 = -32/-4 - 5Divide:                                  3 = 8 - 5Subtract:                              3 = 3

Here we see that 3 does indeed equal 3.

∴ g = -32 is the solution to the equation.

depending on what your teacher is asking for, 25/6 will be your answer or your answer will be 4.16.

Heng was trying to factor 10x^2+5x. She found that the greatest common factor of these terms was 5x5x5, x and made an area model:

Answers

Answer:

Step-by-step explanation:

Given

[tex]Area = 10x^2 + 5x[/tex]

[tex]Length = 5x[/tex]

Required (Missing)

Determine the Width?

Area is calculated as:

[tex]Area = Length * Width[/tex]

Substitute values for Area and Length

[tex]10x^2 + 5x = 5x * Width[/tex]

Factorize the right hand side

[tex]5x(5x + 1) = 5x * Width[/tex]

Divide both sides by 5x

[tex]5x + 1 = Width[/tex]

Hence, the width of the model is 5x + 1
