-(4x - 8y) + 4x + 8y
-4x + 8y + 4x + 8y
16y ← answer
Range is the y-values and since the arrows extend off the graph, we can assume it goes on forever so
answer: (-infinity,+infinity)
make sure it’s parenthesis, not brackets
3x+4y=11
4y=11-3x
Substituting this into x+4y=9
X+11-3x=9
-2x=9-11
-2x=-3
2x=3
X=3/2
Substituting this into x+4y=9
3/2+4y=9
4y=9-3/2
4y=18/2-3/2
4y=15/2
Y=15/2/4
Y=15/8
X=1 1/2
Y=1 7/8
Answer:
Step-by-step explanation:
the answer is 3/4 i think but i may be wrong
