Given the system of equations. We have:
- For (5,0)
Substitute x = 5 and y = 0 in the equations:
Answer: No
- For (-7, -8)
x = -7 and y = -8
Answer: No
- For (3, -4)
This is satisfied for the first equation but not for the second. Therefore it is not a solution to the system.
Answer: No
- For (-2, -2)
Answer: No
Answer:
(-3,-2), (-1,-2), (1,-2)
Step-by-step explanation:
Each point on the plane is of the form (x,y). let's see which points satisfy the inequality
a)
, then (-3,-2) satisfies the inequality.
b)
, then (-2,1) doesn't satisfy the inequality
c)
, then (-1,-2) satisfies the inequality.
d)
, then (-1,2) doesn't satisfy the inequality.
e)
, then (1,-2) satisfies the inequality.
