Answer:

Step-by-step explanation:

I think we need to define domain and range first.

Domain is the set of all x values where the function f(x) exists or is defined.

Range is the set of all y values that will result from substituting all x values (the domain) into the function.

So for g(x) = 2x - 2 we can evaluate g(x) at any point, and we will get a real answer for y.

So the range of g(x) = 2x -2 is also all real numbers, because no matter what value of x is, we can always multiply that number by 2 and subtract 2.

The inequality does not affect the domain and range of linear functions at all. Don't confuse domain and range with a solution to an inequality. These two concepts are different. Domain and range mean all possible values of x and y that could be substituted into the inequality. A solution means all possible values that make the inequality statement true.

The domain as an inequality would be -∞ < x < ∞

The range as an inequality would be -∞ < y < ∞

As a set notation:

Domain {x | -∞ < x < ∞}

Range {y | -∞ < x < ∞}

In interval notation:

Domain (-∞ , ∞)

Range (-∞ , ∞)

End behavior:

As x gets larger and larger, g(x) gets larger and larger as well, and as x gets smaller, g(x) gets smaller too.

Answer:

h=12.5

Step-by-step explanation:

It’s a right triangle, so you can use the Pythagorean Theorem.  

9.2²+8.5²=h²

84.64+72.25=h²

156.89=h²

√156.89=h

h=12.5255

h=12.5

Step-by-step explanation:

The equation [tex]x^{3} - 3[/tex] has x values as 0, [tex]\sqrt{3}[/tex] and -[tex]\sqrt{3}[/tex].

We are given,

3 is subtracted from the cube of a number.

Let the number be x then we can write it as:

 [tex]x^{3}[/tex] - 3

We are to solve for x.

We can write the equation as:

[tex]x^{3}[/tex] - 3  = 0

x ( [tex]x^{2}[/tex]- 3 ) = 0

x = 0 and ( [tex]x^{2}[/tex] - 3 ) = 0

x = 0 and [tex]x^{2}[/tex] = 3

x = 0 and x = ±[tex]\sqrt{3}[/tex]

So we have,

x  = 0, [tex]\sqrt{3}[/tex] and -[tex]\sqrt{3}[/tex]

Thus we have x values as 0, [tex]\sqrt{3}[/tex] and -[tex]\sqrt{3}[/tex].

Step-by-step explanation:

The fourth diagram  show lines that must be parallel lines cut by a transversal

A line is an infinitely long object with no width, depth, or curvature.

Parallel lines  refers to two lines which can be found on the same plane, at an equidistance and does not meet.

A transversal is defined as a line that passes through two lines in the same plane at two distinct points in the geometry.

The fourth diagram has two same-side interior angles that are supplementary (add to 180°).

The converse of the same-side interior angle theorem states that if two lines are cut by a transversal and the same side interior angles are supplementary, then the lines are parallel.

Hence, the fourth diagram  show lines that must be parallel lines cut by a transversal

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

D is the midpoint of CE, then

CD = DE = 0.5CE = 0.5(10x+18) = 5x + 9

So:   5x + 9 = 7x - 1

            -9          -9

        5x  =  7x - 8

        -7x      -7x

       -2x  =  -8

      ÷(-2)       ÷(-2)        

          x  =  4

AC = CE = 10x + 18 = 40 + 18 = 58

BC = 9x - 2 = 36 - 2= 34

AB = AC - BC = 58 - 34 = 24

D is the midpoint of CE, so if you draw a line with those three points, it'll look like C-D-E.

Since DE = 7x-1, which also means CD = 7x-1.

CD + DE = CE, so (7x-1)+(7x-1) = 10x+18.

Therefore, x = 5 and CE = 68.

Since AC is congruent to CE, AC = 68.

Assuming the point B is somewhere between AC.

Since BC = 9x-2 and x = 5, which means BC = 43.

AC - BC = AB, so 68 - 43 = 25.

Therefore, AB = 25

==================================================

Explanation:

Consider the expression x^2

If x were some negative number, say x = -3, then

x^2 = (-3)^2 = 9 which is a positive result.

Picking any negative number for x will make x^2 positive.

We can think of it like this

(-3)^2 = (-3)*(-3) = 9

The two negatives multiply to a positive.

This also happens with exponents 4,6,8, etc. Any even exponent will have an even number of negative signs, all of which cancel out.

I apologize if it is wrong.

The repeating decimal 16.666... as a fraction is 50/3.

We have,

Consider

x = 16.6666... ______(1)

Multiply 10 on both sides.

10x = 10 x 16.6666...

10x = 166.666..... ______(2)

Subtract (1) from (2).

10x - x = 166.666..... - 16.666...

9x = 150

x = 150/9

x = 50/3

Thus,

The repeating decimal as a fraction is 50/3.

x=16

Step-by-step explanation:

its C

Answer:

x=16

Step-by-step explanation:

First of all we want to distribute 0.5 on 5x and -8

so we are going to divide by 2

1.5x + 12 = 2.5x -4

now we want to put the variables on one side and the numbers on the other side of the equal sign

and to

1.5x +12 = 2.5x -4

        -12             -12

1.5x = 2.5x - 16

now we want to move the variable that is on the right to the left side

1.5x = 2.5x - 16

-2.5x  -2.5x

-x = -16

change the signs and the answer is

x=16
