Answer:
y=-2x+5
Step-by-step explanation:
y=-2x+b
7=2+b
b=5
Therefore, y=-2x+5
1)t=S/U=2.4/12=0.2
2)t=S/U=8.4/36=0,23
3)0.23-0.2=0.03
Answer:
x+√y
Step-by-step explanation:
You should try both points
put x=5/2 and y=3
5-2=3
the first one is on the graph
put x=3/2 and y=20
3-40/3≠3
the second one is not on the graph
