Solve 10 6(–9 – 4x) = 10(x – 12) 8.
Irina-Kira [14]
10 + 6(-9 - 4x) = 10(x - 12) + 8
10 - 54 - 24x = 10x - 120 + 8
-44 - 24x = 10x - 112
10x + 24x = -44 + 112
34x = 68
x = 68/34 = 2

Solve the following questions<br>​
Simora [160]

Start with

\dfrac{2x-1}{2x+1}-\dfrac{2x+1}{2x-1}

Observe that this implies that the domain is

2x+1,\ 2x-1\neq 0 \implies x \neq \pm\dfrac{1}{2}

The least common denominator is

\dfrac{2x-1}{2x+1}-\dfrac{2x+1}{2x-1} = \dfrac{(2x-1)^2-(2x+1)^2}{(2x+1)(2x-1)}=\dfrac{-8x}{4x^2-1}

In the right hand side, we have

-2\dfrac{2}{3}=-\left(2+\dfrac{2}[3}\right)=-\left(\dfrac{6}{3}+\dfrac{2}{3}\right)=-\dfrac{8}{3}

So, the equation becomes

-\dfrac{8x}{4x^2-1}=-\dfrac{8}{3} \iff \dfrac{x}{4x^2-1}=\dfrac{1}{3}

Multiply both sides by 3:

\dfrac{3x}{4x^2-1}=1 \iff 3x=4x^2-1 \iff 4x^2-3x-1=0

This equation has solutions

x=-\dfrac{1}{4},\quad x=1

Which are compliant with the domain of the equation

Can any equation in point-slope form also be written in slope-intercept form?
Gekata [30.6K]

Answer:

Yes

Step-by-step explanation:

The way the equation is written in point-slope form is:

y-y1=m(x-x1)

The way we write an equation in slope-intercept form is:

y=mx+b

We can change point-slope form to slope-intercept form by first distributing the m and then adding y1 to both sides of the equation. When we do this we will get:

y=mx-(m*x+y1) where (m*x+y1) = b

which is now in slope intercept form.
