Answer:
x=0, y=2. (0, 2).
Step-by-step explanation:
3x+2y=4
8x-3y=-6
---------------
3(3x+2y)=3(4)
2(8x-3y)=2(-6)
-----------------------
9x+6y=12
16x-6y=-12
----------------
25x=0
x=0/25
x=0
3(0)+2y=4
0+2y=4
2y=4-0
2y=4
y=4/2
y=2
Answer:
First option:
Second option:
Fourth option:
Step-by-step explanation:
Rewrite each equation in the form and then use the Discriminant formula for each equation. This is:
1) For :
Then:
Since this equation has no real solutions, but has two complex solutions.
2) For :
Then:
Since this equation has no real solutions, but has two complex solutions.
3) For :
Then:
Since this equation has one real solution.
4) For :
Then:
Since , this equation has no real solutions, but has two complex solutions.
It shows you the exact distance from each number and it's easier to find out how far apart they are.
