What value of x is in the solution set of 4x – 12 5 16 + 8x?

Mathematics

TEA [102]3 years ago
8 0

Answer:

4x-12= 16 +8x

And we can subtract 4x in both sides and we got:

-12 = 16 +4x

Now we can subtract in both sides 16 and we got:

-28 = 4x

And if we divide both sides by 4 we got:

x = -7

And the best solution would be:

-7

Step-by-step explanation:

For this case we assume the following equation:

4x-12= 16 +8x

And we can subtract 4x in both sides and we got:

-12 = 16 +4x

Now we can subtract in both sides 16 and we got:

-28 = 4x

And if we divide both sides by 4 we got:

x = -7

And the best solution would be:

-7

12. Find the value of x.<br> HELP PLS HELP
xenn [34]

Answer:

x = 16

Step-by-step explanation:

 SR = ST ⇒ Two sides are equal. So, ΔSRT is an isosceles triangle.

The angles opposite to equal sides are equal.

  ⇒  ∠STR  = ∠R

       ∠STR = 4x - 28

Linear pair: If a ray stands on a line, then the adjacent angles are supplementary and they are called linear pair

∠STR + ∠STU = 180°    {linear pair}

4x - 28 + 9x = 180

4x + 9x - 28  = 180      {Combine like terms}

       13x- 28 = 180

Add 28 to both the sides

          13x    = 180 + 28

           13x  = 208

Divide both sides by 13

              x = 208/13

  \sf \boxed{x = 16}

What are three other expressions that are equivalent to 8x-12
Kisachek [45]

Answer:

2(4x-6)

4(2x-3)

8(x-3/2)

Step-by-step explanation:

find all factors of 8 other than 1, you should have 3

divide the whole equation by the factor then multiply by the factor

2(8x-12)/2 = 2(4x-6)

4(2x-3)

8(x-3/2)

What is the equation of the line shown in this graph? <br><br> The points are (-2, 2) and (-2, -3)
KengaRu [80]

\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{-2}~,~\stackrel{y_2}{-3}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-2}{-2-(-2)}\implies \cfrac{-3-2}{-2+2}\implies \stackrel{und efined}{\cfrac{-5}{0}}


so our slope is undefined, that means a vertical line, check the picture below
