Well, if you simplify complex fractions, they essentially turn into a ratio and a simple fraction, which you can multiply out if needed to , for example, separate a variable

Describe how the graphs of y=x and y=x-15 related

Sholpan [36]

They have the same slope
in y=mx+b form
m=slope
b=y-intercept
the equations are
y=1x+0 and y=1x-15
the slopes are the same, the y intercepts are the ones that changed
since they have the same slope, they are paralel to each other

What value ofx is in the solution set of 3(x-4)>5x +2?

kvv77 [185]

$\boldsymbol{\sf{3(x-4) > 5x +2 }}$

Use the distributive property to multiply 3 by x−4.

$\boldsymbol{\sf{3x-12 > 5x+2 }}$

Subtract 5x on both sides.

$\boldsymbol{\sf{3x-12-5x > 2 } }$

Combine 3x and −5x to get −2x.

$\boldsymbol{\sf{-2x-12 > 2 }}$

Add 12 to both sides.

$\boldsymbol{\sf{-2x > 2+12 \ \longmapsto \ \ [Add \ 2 +12]}}$

$\boldsymbol{\sf{-2x > 14}}$

Divide both sides by −2. Since −2 is < 0, the inequality direction is changed.

$\boldsymbol{\sf{x < \dfrac{14}{-2} \ \ \longmapsto \ \ \ [Split]}}$

$\boxed{\boldsymbol{\sf{x < -7 }}}$

So in the <u>inequality 3(x-4)>5x +2</u>, the value of x is -7.
