I think you have an extra plus sign.

<span>-4x -  2y = -12
 4x + 8y = -24

Add the equations to eliminate x.

6y = -36

y = -6

Now multiply the first equation by 4 and add to the second equation.

-16x - 8y = -48
  4x + 8y = -24
--------------------
-12x        = -72

x = 6

Solution: x = 6 and y = -6

Since the 4x and -4x cancel out, this is what you get:
6y=-36

HELP PLEASE ASAP!!!!
vodomira [7]

Answer:

I may be wrong, but I learned that the first slot would be "terms". 4:3 would be an example of a ratio so it couldn't be ratio and a difference is subtracting.

The second slot would not be a geometric sequence because it is not correctly placed on the number line.

Therefore, the answers would be "terms" and "is not"
