Answer:
jelly=3.75
trail=2.75
Step-by-step explanation:
The form is y=mx+b
3x=-2y+4 (add 2y)
3x+2y=4 (subtract 3x)
2y=-3x+4 (divide by 2)
y= -2/3x+2
Y=mx+b
y=(1200-2x)/3
y=1200/3-2/3x
y=400-2/3x
y=-2/3x+400
Answer: The answer is 2.
Step-by-step explanation: If you have 2 minuses together, then that actually means a plus. -7+9 is 2.
