Coordinates are written in the form (x,y), x being a certain length along the horizontal x axis and y being a certain height along the vertical y axis. Positive y numbers are in the top half of the plane and negative y numbers are on the bottom. Positive x numbers are on the right side of the plane and negative x numbers are on the left. Therefore, (3,-7) would be 3 across to the right from the origin (where the x and y axes intersect) at (3,0) and 7 downwards from that point to (3,-7).
Answer:
I believe that would be 12 because
Step-by-step explanation:
if 2x - 7y = 10
then if you were to add two to that it would be 12
Answer:
1
Step-by-step explanation:
(3x3-2)-10=(9+2)-10=11-10=1
Answer:
b. 2 and 3
Step-by-step explanation:
Solve for x
Now factor
It would be -2 and -3 because they add up to -5 and multiply to be 6 (a negative times a negative always equal a positive)
Don't forget that it's still equal to 0
Now solve for x in both equations
add 2 to both sides add 3 to both sides
