Solve the equation<br> 9|9-8x|=2x+3 show work.

Nadya [2.5K]

As you already know, an absolute value expression is a piece-wise in effect.

$\bf 9|9-8x|=2x+3\implies |9-8x|=\cfrac{2x+3}{9}\\\\\\ 
\begin{cases}
+(9-8x)=\cfrac{2x+3}{9}\\\\
-(9-8x)=\cfrac{2x+3}{9}
\end{cases}\\\\
-------------------------------\\\\
9-8x=\cfrac{2x+3}{9}\implies 81-72x=2x+3\implies 78=74x
\\\\\\
\cfrac{78}{74}=x\implies \cfrac{39}{37}=x\\\\
-------------------------------\\\\
-(9-8x)=\cfrac{2x+3}{9}\implies -9+8x=\cfrac{2x+3}{9}
\\\\\\
-81+72x=2x+3\implies 70x=84\implies x=\cfrac{84}{70}\implies x=\cfrac{6}{5}$

Divide..................

Masja [62]

Answer:

option-A

Step-by-step explanation:

we are given

Dividend is

$6x^2-19x+10$

Divisor is

$2x-5$

we can use long division method

we get

Remainder is

=0

Quotient is

$3x-2$

so, we can write as

$\frac{6x^2-19x+10}{2x-5}=3x-2+\frac{0}{2x-5}$

$\frac{6x^2-19x+10}{2x-5}=3x-2$
