Distance Rate times Time
320= R 5.25
R= 60.9
R= 61 mph
Where are the expression.
I would say -3+5
Answer:
Step-by-step explanation:
y=mx+b
m=(y2-y1)/(x2-x1)
m=(90-65)(/(200-100)=25/100=1/4
y=x/4+b, using point (100,65)
65=100/4+b
65=25+b
b=40
y=x/4+40 or more neatly
y=(x+160)/4
Following these steps you should have no problem with second problem.
