X-124=9(2x+3)-15 ???

musickatia [10]

Answer:

x = - 8

Step-by-step explanation:

x - 124 = 9(2x + 3) - 15

x - 124 = 18x + 27 - 15

x - 124 = 18x + 12

x - 124 + 124 = 18x + 12 + 124

x = 18x + 136

x - 18x = 18x - 18x + 136

- 17x = 136

- 17x ÷ - 17 = 136 ÷ - 17

x = - 8

What is the slope of the line through (-7,-2) and (−6,7)?

Murrr4er [49]

Answer:

slope = 9

Step-by-step explanation:

To find the slope of a line that passes through a pair of points, use the slope formula, $m = \frac{y_2-y_1}{x_2-x_1}$ . Substitute the x and y values of (-7,-2) and (-6,7) into the formula and simplify:

$m = \frac{(7)-(-2)}{(-6)-(-7)} \\m = \frac{7+2}{-6+7} \\m = \frac{9}{1} \\m = 9$

So, the slope is 9.
