elena-14-01-66 [18.8K]

<h2>Answer:</h2>

$x = \frac{22}{3}$

<h3>alternative form:</h3>

$x = 7 \frac{1}{3} \: or \: x = 7.33333333333$

<h2>Step-by-step explanation:</h2>

$2(3x + 1) = 17 - 3( x - 17) \\ distribute \\ \\ 6x + 2 = 17 - 3x + 51 \\ add \: 3x \: from \: both \: sides \\ \\ 9x + 2 = 17 + 51 \\ add \: 17 \: to \: 51 \\ \\ 9x + 2 = 68 \\ subtract \: 2 \: from \: both \: sides \\ \\ 9x = 66 \\ divide \: both \: sides \: by \: 9 \\ \\ x = \frac{22}{3}$

HELP ASAP WILL GIVE BRAININST IF:

DiKsa [7]

Answer:

<em><u>slope is -7/8</u></em>

Step-by-step explanation:

ok

first remember these to formulas:

$m= \frac{y2-y1}{x2-x1}$

and

$y-y1 = m(x-x1)$

now insert the points:

$\frac{-3-4}{3-(-5)}$ = -7/8

slope intercept form:

y - 4 = -7/8(x - (-5)

y - 4 = -7/8(x + 5)

y = -7x/8 - 3/8

Have a nice day!

and if you have a question or if I did anything wrong please tell me.
