2. JI. has coordinates J(-6, 1) and Z(-4, 3). Find the coordinates of the midpoint.​
AleksandrR [38]

Answer:

(- 5, 2 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( \frac{x_{1}+x_{2}  }{2}, \frac{y_{1}+y_{2}  }{2} )

Here (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (- 4, 3) thus

midpoint = \frac{-6-4}{2}, \frac{1+3}{2} ) = ( \frac{-10}{2}, \frac{4}{2} ) = (- 5, 2 )

HELP! will mark BRAINILEST !
Sedbober [7]
I like A as the best one

420 = 100*price - (fixed costs)
220 = 60*price - (fixed costs)

If we subtract one from the other one, we get 200 = 40*price, price = 5
that said, fixed costs are 500 - 420 = 80

Now if we move -220 to the right in Answer A, we'll get:

y = 5x -300 + 220 = 5x - 80

So it looks like A describes the model best

x + 232° = 360°

x = 360° - 232°

x = 128°
