Answer:

x= -2 and y=1

Step-by-step explanation:

Given equations:

-3x - 4y = 2

3x + 3y = -3

Adding these two equations, we get:

3y - 4y = -1 ⇒ y=1

⇒ 3x + 3(1) = -3 ⇒ x=-2

Points A,B, and C are collinear. Points M and N are the midpoints of segments AB and AC. Prove that BC = 2MN

irinina [24]

Look at the picture.

1)|AM| = |MB| = x
|AN| = |NC| = y
|BC| = 2y - 2x = 2(y - x)
|MN| = y - x
Therefore |BC| = 2|MN|
2)|AM| = |MB| = x
|AN| = |NC| = y

|BC| = 2y - 2x = 2(y - x)
|MN| = y - x
Therefore |BC| = 2|MN|

Find the slope of the line graphed in the diagram and choose the correct answer from the choices below. The two intercepts are (

kvasek [131]

The correct slope is -5/2.

The formula for slope is

m = (y₂-y₁)/(x₂-x₁)

The y-coordinate of the second point is 0, and the y-coordinate of the first point is 2. The x-coordinate of the second point is 0.8 and the x-coordinate of the first point is 0:

m = (0-2)/(0.8-0) = -2/0.8 = -2 ÷ 8/10 = -2 × 10/8 = -2/1 × 10/8 = -20/8 = -5/2
