\frac{2}{3} (x - 4) = 2x \\  \frac{2}{3} x -  \frac{8}{3}  = 2x \\  \frac{2}{3} x - 2x =  \frac{8}{3}  \\  \frac{2}{3} x -  \frac{6}{3} x =  \frac{8}{3}  \\   \frac{ - 4}{3} x =  \frac{8}{3}  \\  - 12x = 24 \\ x =  \frac{24}{ - 12}  \\ x =  - 2

(5,3) and (-2,-3) slope intercept form

\bf (\stackrel{x_1}{5}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{-2}~,~\stackrel{y_2}{-3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-3}-\stackrel{y1}{3}}}{\underset{run} {\underset{x_2}{-2}-\underset{x_1}{5}}}\implies \cfrac{-6}{-7}\implies \cfrac{6}{7}

Please help! I need this paper done before my class tomorrow! Thank you!
BabaBlast [244]

Answer:

x=7 and m<LMN = 120

Step-by-step explanation:

if MO bisects LMN then 13x - 31 must be equal to x + 53

13x - x = 53 + 31

12x = 84

x = 7

and

13x - 31 + x + 53 = m<LMN

14x + 22 = m<LMN

since x is 7

14×7 + 22 = 120

What is 0.71 as a quotient of integers?
Blababa [14]

0.71 is read "seventy-one hundredths".

So, you put 71 over 100.

\frac{71}{100}

71 is prime, so no simplification can be done.

B

Step-by-step explanation:

f(x) = sqrt(x) + 9

f(x) - 9=sqrt(x)

f^(-1)(x)=(x-9)^2 and it's domain is greater than 0
