Answer:

we conclude that the first step is to find the greatest common factor (GCF).

Hence, option C is correct.

Step-by-step explanation:

[tex]16x^2\:-36[/tex]

As 4 is the greatest common factor of the expression, so factor out common term 4:

i.e.

[tex]16x^2\:-36=4\left(4x^2-9\right)[/tex]

Thus, the first step is to find the greatest common factor (GCF)

Now, solving the remaining portion

[tex]16x^2\:-36=4\left(4x^2-9\right)[/tex]

as (2x+3) and (2x-3) are the factors of (4x²-9)

i.e. (4x²-9) = (2x+3) (2x-3)

Thus, the expression becomes

[tex]16x^2\:-36=4\left(2x+3\right)\left(2x-3\right)[/tex]

Therefore, we conclude that the first step is to find the greatest common factor (GCF).

Hence, option C is correct.

Remark

The point about the question is that the two sides are marked as equal.

Equation

3x + 5 = 5x + 1                  Subtract 3x from both sides

Solution

3x - 3x + 5 = 5x - 3x + 1   Combine like terms

5 = 2x + 1                          Subtract 1 from each side

5-1 = 2x +1 - 1                    Combine

4 = 2x                               Divide by 2

4/2 = 2x/2

x = 2

Answer:

2^1 ?   10^x

Step-by-step explanation:

1 can be written as a power with base 2 as [tex]2^0[/tex].

1 can be written as a power with base 10 as [tex]10^0[/tex].

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To write the number 1 as a power with base 2,

We can use the following formula:

[tex]2^0[/tex] = 1

Therefore,

1 can be written as [tex]2^0[/tex].

To write the number 1 as a power with base 10, we can use the following formula:

[tex]10^0[/tex] = 1

Therefore,

1 can be written as [tex]10^0[/tex].

Thus,

1 can be written as a power with base 2 as [tex]2^0[/tex].

1 can be written as a power with base 10 as [tex]10^0[/tex].

Answer:

6.25 divided by 0.025 is 250

Answer:

120 home runs.

Step-by-step explanation:

Let x be the number of home runs after playing 1272 games.

We have been given that Derek Jeter, the short stop for the New York Yankees, a major league baseball team, played in 159 games in 2012 and hit 15 home runs.

Let us find the probability of hitting home runs in next game.

To find the total number of home runs Derek will hit in his career, we will use relative probability, which is the ratio of the occurrence of a singular event and the total number of outcomes.

So we can set a proportion as:

Let us multiply both sides of our equation by 1272.

Therefore, Derek Jeter will hit approximately 120 home runs in his career.

In his career, Derek Jeter will probably hit 120 home runs.

A proportion is an equation that sets two ratios at the same value.

Let x be the number of home runs after playing 1272 games.

And given, Derek Jeter hits 15 home runs in 159 games.

To find the number of home runs he hit in 1272 games,

x =  1272 x 15 / 159

x = 120

And to find the proportion:

15x = 120

x = 120/15

x = 8

We can calculate the Cross Product this way:

cross product with angle and unit vector

a × b = |a| |b| sin(θ) n

Therefore, Derek Jeter will hit approximately 120 home runs in his career.

Answer:

Break-even point in units= 500

Step-by-step explanation:

Giving the following information:

Fixed costs= $100,000

Unitary variable cost= $100

Selling price per unit= $300

To calculate the break-even point in units, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 100,000 / (300 - 100)

Break-even point in units= 500

Answer:

Step-by-step explanation:

m∠5 +m∠6 = 180° ( the angles form a line)

m∠2 + m∠3 = m∠6 ( exterior angle is the sum of 2 not adjacent angles)

m∠2+m∠3+m∠5= 180° (sum of angles in a triangle is 180°)

Answer: The sum of three consecutive even integers is 24. The integers are 6 (from the x) , 8 (from the x + 2), and 10 (from the x + 4).

Step-by-step explanation:

Answer:

x = 2.

Step-by-step explanation:

Start by distributing the 3 to what is in the parentheses.

3 times 2x = 6x.

3 times -3 = -9.

So now you have:

6x - 9 = 7 - 2x.

You want to get the x variables on one side.

So add the 2x to both sides.

8x - 9 = 7.

You want to get x by itself.

So add 9 to both sides.

8x = 16.

x = 2.

2 is a prime number and a integer

24 is a whole number and an integer

1 is an integer and a whole number

0 is a rational, whole, integer and real number

and seven is a whole and integer

Answer:

He is incorrect.

Step-by-step explanation:

The range values cannot be greater than the domain values because of the known mathematical fact that all inputs (domain) can only have one output (range). This mathematical fact proves that the range can only be equal to the amount of inputs, not greater. To show why let's look at an example.

Ex:

Inputs:     Outputs:

   1                   2

   3                  2

   6                  2

Using that example we can already conclude that the domain values can be greater than the range values because each of the different inputs can have the same outputs as shown in the table above. But the thing with range is you can't have more than one output for the inputs. For example 1 (input) = 2 output and this will always equal 2 no matter what. You cannot have the inputs of 1 and have different outputs 2 and 4. Since you cannot have more than one output for an input it makes the amount of range values impossible to be greater than the domain values.
