The algorithm is tripping! It won't let me post a legit explanation. Sorry!
Answer:
x+y=8
Step-by-step explanation:
2(3x+y=20)
6x+2y=40
2x-2y=8
8x=48
x=6
18+y=20
y=2
Start by simplifying by dividing both numerator and denominator ;
21/11
=1 10/11
The number in the parenthesis is the X value and they are looking for what the Y value is at that specific X.
So when you look at f(-2), find the Y value where the line crosses.
At X-2, the line crosses Y at -2
At X = 2, the line crosses at Y = 2
At X = 4, the line crosses at Y = 1
The answer is -2,2,1
