What can each term of the equation be multiplied by to eliminate the fractions before solving?
1/2x-5/4+2x=5/6+x

Answer:

Whole numbers

Explanation:

0 is a whole number, but not a natural number. Whole numbers include all natural numbers and 0.

The inverse function will be h⁻¹(x) = {(–5, 3), (–7, 5), (–9, 6), (–12, 10), (–16, 12)}. Then the correct option is B.

Suppose that the given function is

f:X → Y

Then the inverse of the considered function will be

f⁻¹: Y → X

The function h(x) is given below.

h(x) = {(3, –5), (5, –7), (6, –9), (10, –12), (12, –16)}

Then the coordinate of the inverse function gets swapped.

h⁻¹(x) = {(–5, 3), (–7, 5), (–9, 6), (–12, 10), (–16, 12)}

Then the correct option is B.

GCF is a way to simplify a polynomial by separating out one factor.

GCF

GCF stands for greatest common factor. This means the GCF is the largest number that is a factor of each term.

For example, the GCF of 15 and 25 is 5 because that is the greatest common factor between the 2 numbers.

Finding the GCF

To find the GCF, first look at the coefficients of each term.

These numbers have no shared factors besides 1, which doesn't help because factoring out 1 does nothing.

However, next, we can move on to the variables. You can factor out variables the same way you do constants.

Factoring Out X

The question states that we only need to do GCF to solve. So, we can just factor out x. Remember that factoring is like dividing each term by x.

The completely factored expression is:

Here we have divided each term by x and then added x as a new factor in the expression.

The answer to the person with the largest dollar sales in December is d. They each had the same dollar amount in sales.

The sales of the salary + commission employee is:

= (4,400 - 2,000) / 3%
= $80,000

The sales of the straight commission employee is:

= 5,600 / 7%

= $80,000

The sales of the graduated commission employee is:

The amount earned on the first $40,000 is:

= 5% x 40,000

= $2,000

The rest of the sales is therefore:

= (5,200 - 2,000) / 8%

= $40,000

The total sales for this employee is:

= 40,000 for 5% commission + 40,000 for 8%

Answer:

y = 139

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

110° is an exterior angle of the triangle , then

3x + 2x - 5 = 110

5x - 5 = 110 ( add 5 to both sides )

5x = 115 ( divide both sides by 5 )

x = 23

then

2x - 5 = 2(23) - 5 = 46 - 5 = 41

y and 2x - 5 are a linear pair and sum to 180° , so

y = 180 - 41 = 139

Answer:

I got 139

Someone correct me if I'm wrong.

Step-by-step explanation:

(2x-5) + 3x + 70 = 180

Collect liketerms. Take away 70 from both sides and add 5.

5x=115

x=23

2(23) -5 = 41

180-41 = 139

y = 139

Answer:

XY = 6

Step-by-step explanation:

using the sine ratio in the right triangle and the exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{XZ}[/tex] = [tex]\frac{XY}{12}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2 XY = 12 ( divide both sides by 2 )

XY = 6

The length of the side XY in ΔXYZ is 6 units.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

In reference to the angle of 30° opposite side is XY and the hypotenuse is 12 units.

We know, sin = opposite/hypotenuse.

Therefore, sin30° = XY/12.

1/2 = XY/12.

XY = 12/2.

XY = 6 units.

Answer:

Step-by-step explanation:

   1) -4 + 3x = 4x - 8

        Add 4 to both sides

      -4 + 3x + 4 = 4x - 8 +  4

               3x     = 4x - 4

Subtract 4x from both sides,

        3x - 4x = -4x + 4x - 4

              -x   = -4

                [tex]\sf \boxed{\bf x = 4}[/tex]

2) -5x - 8 = 2

Add 8 to both sides

 -5x - 8 + 8 = 2 + 8

            -5x  = 10

Divide both sides by (-5)

            [tex]\sf \dfrac{-5}{-5}x =\dfrac{10}{-5}[/tex]

3) 12r - 14 = 5(2-r)

    12r - 14 = 5*2 - 5*r

     12r - 14 = 10 - 5r

Add 14 to both sides

 12r - 14 + 14 = 10 - 5r + 14

             12r  = 24 - 5r

Add 5r to both sides

        12r + 5r = 24

               17r = 24

Divide both sides by 17

                 r = 24/17

4) 3x - 8 = -(17 + 2x)

  3x - 8 = -17 - 2x

Add 8 to both sides

3x - 8 + 8 = -17 - 2x + 8

           3x = -9 - 2x

Add 2x to both sides

      3x + 2x = -9

            5x  = -9

Divide both sides by 5

Answer:

x = 4  &  x = -2

Step-by-step explanation:

For rational functions (functions which themselves are a fraction, with polynomial pieces in the numerator and polynomial pieces in the denominator), these functions have "discontinuities" anywhere the denominator is equal to zero.  Usually, those discontinuities are "vertical asymptotes".  Occasionally, those discontinuities are "holes".

A discontinuity is a "hole," only if both the numerator AND the denominator are zero for that same value of x.  If that value of x doesn't make the numerator zero (it only makes the denominator zero), the discontinuity is just a vertical asymptote.

To find the discontinuities, we'll be making an entirely separate equation.  It's not the function, it's not using algebra to change both sides of the equation/function we started with ... it's pretty much just like scratch work to figure out something that you can use later (although, your teacher may want to see your work on how you found them).

The equation we need for this is the denominator of our rational function set equal to zero:

[tex](x-4)(x+2)=0[/tex]

Note, this equation doesn't have a denominator.  It's not the original function.  It's like scratch work.  This equation is designed as if we want the denominator of our function to be zero, and to find the values of x that will make us divide by zero in the original function.

There are many ways to solve this equation.  The easiest is remembering the zero product property.  The Zero Product property states that if the product of two things is equal to zero, then at least one of the original things had to be zero:  [tex]\text{If }a*b=0,\text{ then }a=0\text{ or }b=0 \text{ (or both)}[/tex]

Noting that our equation is a product of two things, and is equal to zero, the zero product property allows us to separate our equation into two equations:

[tex]x-4=0, \text{ or } x+2=0[/tex]

Solving each equation by isolating x, by adding or subtracting the relevant number from both sides of the equations:

[tex]x=4, \text{ or } x=-2[/tex]

So these values of x will make the denominator of the original function zero.  These are both discontinuities of the function, so while when we were solving for values of x that would make the denominator zero, it was appropriate to say "or", we know that both of these values are discontinuities and now we list them both saying "and":

Discontinuities: [tex]x=4 \text{ and } x=-2[/tex]

But wait!  Are they holes, or are they just vertical asymptotes?  Do we have one of each?

Testing to see if the discontinuities are asymptotes:

To test and see if the discontinuities we've found are holes, we need to substitute them into the numerator of the original function, and see the result.... but just the numerator (we already know they will make the denominator zero, and we can't divide by zero)

Since the numerator is just x, we're checking to see if 4=0, or if -2=0.  They don't.  So, for this function, both of the discontinuities are vertical asymptotes.
