Answer:

In my opinion, it would be 'y', since it is already on its own (in the first equation) without any coefficients.

Answer:

Step-by-step explanation:

x because if you multiply the first equation by 2 and add the result to equation 2 , the y's will cancel out.

2x + y = 9 Times 2:-

4x + 2y = 18

3x - 2y = 17 Adding:-

7x = 35

x = 5.

Find the midpoint between P(-8, -7) and K(11,5).

irakobra [83]

Answer:

M(3/2, -1)

Step-by-step explanation:

$(\frac{x_1+y_1}{2},\frac{x_2+y_2}{2})\\ \\(\frac{-8+11}{2},\frac{-7+5}{2})\\\\(\frac{3}{2},\frac{-2}{2})\\\\(\frac{3}{2},-1)$

Therefore, the midpoint between P(-8, -7) and K(11,5) is M(3/2, -1)
