You have to solve for X. You add 8 to both sides which should give you the new equation -6=2x. After that you have to divide 2 from both sides.

Your answer is X=-3.

Solve for m.<br> 2=m/2−7<br> two step equation

Svetradugi [14.3K]

2=m/2−7

Simplify both sides of the equation.

2=m/2−7

2=1/2m+−7

2=1/2m−7

Flip the equation.

1/2m−7=2

Add 7 to both sides.

1/2m−7+7=2+7

1/2m=9

Multiply both sides by 2.

2*(1/2m)=(2)*(9)

m=18

Two points A (-2, 9) and B (4, 8) lie on a line l. (i) Find the slope of the line l. (ii) Find the coordinates of the midpoint o

snow_lady [41]

Answer:

The slope of the line is: $\frac{-1}{6}$

The midpoint is located in (1, 8.5)

The distance between the points is 2.236

Step-by-step explanation:

The slope of the line can be calculated by:

$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8-9}{4+2} = \frac{-1}{6}$

The midpoint can be calculated by:

$midpoint = (\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})\\midpoint = (\frac{-2 + 4}{2}, \frac{9 + 8}{2})\\midpoint = (1, 8.5)$

The distance between two points is:

$distance = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\\distance = \sqrt{(-4+2)^2 + (8 - 9)^2}\\distance = \sqrt{(-2)^2 + (-1)^2}\\distance = \sqrt{4 + 1} = \sqrt{5} = 2.236$
