Step-by-step explanation:
I'm doing the test right now
Idk what linear combination is but you can solve this way:
3x+y=4
-2x-y=-5
x=-1
3(-1)+y=4
-3+y=4
y=7
So x=-1 and y=7
Answer:
A
Step-by-step explanation:
The correct answer is A.
Try breaking the shape into other shapes that you can find the area for and then adding them together.
Answer:
x>-1
Step-by-step explanation:
solve this normally like a linear equation
3x + 1 >x-1
collect like terms
3x-x>-1-1
2x>-2
x>-2/2
x>-1
