If 2x - 4= 16 for some value of x, then
what is the value of x + 2 for the same
value of x?

Answer:

(x + 3) (x^2 - 6)

Step-by-step explanation:

Factor the following:

x^3 + 3 x^2 - 6 x - 18

Factor terms by grouping. x^3 + 3 x^2 - 6 x - 18 = (x^3 + 3 x^2) + (-6 x - 18) = x^2 (x + 3) - 6 (x + 3):

x^2 (x + 3) - 6 (x + 3)

Factor x + 3 from x^2 (x + 3) - 6 (x + 3):

Answer: (x + 3) (x^2 - 6)

I believe the answer you are looking for is 2.4.

Solution:

n over 3/10-2=6

n over 3/10=8

Multiply 3/10 and 8

You will get 2.4.

Answer:

[tex] - 62[/tex]

Step-by-step explanation:

[tex]5 \times ( - 4) - (( - 6) - 7) \\ = - 20 - 42 \\ = - 62[/tex]

[tex]$f(x)+f(x+1) \stackrel{1}{=} 3^x+3^{x+1} \stackrel{2}{=} 3^x+3^x\cdot3^1\stackrel{3}{=}3^x+3\cdot3^x\stackrel{4}{=}4\cdot3^x\stackrel{5}{=}4\cdot f(x)[/tex]

1) Substitution from definition.

2) We use [tex]$x^{a+b}=x^a\cdot x^b[/tex]

3) We are changing the order of 3 and [tex]3^x[/tex].

4) We add 1 and 3 [tex]3^x[/tex] and we get [tex]4\cdot 3^x[/tex]

5) Substitution from definition (but the other way than at the beginning).

Answer:

n(number of tiles) x 3 - 2

Step-by-step explanation:

times mean multiplication and minus mean subtraction, I hope this helps.

An equation is formed of two equal expressions. An equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

As stated by Sarah that "the number of tiles in each figure was always 3 times the step number minus 2", this can be written in the form of an equation as shown below.

Number of tiles = [3 × (Number of steps)] - 2

Assume that the number of tiles is represented by y, while the number of steps can be written as x. Therefore, we can write the equation as,

y = 3x - 2

Now, let's check the equation,

When the number of steps is 3, the number of tiles is 7.

y = 3(3) - 2

y = 9 - 2

y = 7

Since the number of tiles is the same, therefore, the equation is correct.

Hence, an equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

1/3(21y+39)=-26 can be simplified into

7y +13 = -26

Next, subtract 13 from both sides

7y= -39

Now divide both sides by 7

Your answer is y=-39/7

Answer:

y = -7

Step-by-step explanation:

1/3 (21y+39) = -36

Distribute

7y +13 = -36

Subtract 13 from each side

7y+13-13 = -36-13

7y = -49

Divide each side by 7

7y/7 = -49/7

y = -7

- 6[tex]x^{4}[/tex] + 14x³ + 8x² - 18x - 10

Step-by-step explanation:

Given

(3x² - 4x - 5)(- 2x² + 2x + 2)

Each term in the second factor is multiplied by each term in the first factor, that is

3x²(- 2x² + 2x + 2) - 4x(- 2x² + 2x + 2) - 5(- 2x² + 2x + 2) ← distribute parenthesis

= - 6[tex]x^{4}[/tex] + 6x³ + 6x² + 8x³ - 8x² - 8x + 10x² - 10x - 10 ← collect like terms

= - 6[tex]x^{4}[/tex] + 14x³ + 8x² - 18x - 10

Answer:

Step-by-step explanation:

The set of all real numbers except for 100 in set builder notation (assuming the variable is x) is:

The very first x represents the variable.

The second with the R represents the number. Here, we want all real numbers.

And the third is the constraint. We want all real numbers except for 100.

Answer:

{ x | x ∈ R, x ≠ 100 }

Step-by-step explanation:

Real numbers (R) include all rational and irrational numbers.

Hence, If we need to write it in set-builder notation, we will write as:

{ x | x ∈ R, x ≠ 100 }

In words : "x such that x belongs to R, x is not equal to 100"

This shows that x is any real number except for 100.
