Travel_Word_Problems/387223: Two cyclists start biking from a trail's start 3 hours apart. The second cyclist travels at 10mph and starts 3hrs after the first cyclist who is traveling at 6mph. How much time will pass before the second cyclist catches up with the first from the time the second cyclist started?
I have tried making a chart:
biker : rate : time : distance
1 : 6mph : T : 6T
2 : 10mph : T+3 : 10(T+3) then 6T=10(T+3)...but that doesnt work out.

Quadratic_Equations/387209: y=x2+4x+3 Graph using Quadratic Equation. I have a calculator but I really don't know how to use it well. I know how to go to the Y= screen. How do you set this up and graph it.
I have one more question, Question Solve with the slope-intercept form of equation (-7,7) and(0,-3).
this is what I got.
(-7,7) (0,-3)
m=7-3/0-7
=4/-7=4/7
y=(4/7)x+b
using (0,-3) to solve for b
-3=b
y=(4/7)x-3 my answer

You can put this solution on YOUR website!I think you lost a minus sign somewhere.
m=(-3-+7)/(0--7)
m=-10/+7
m=-10/7
----------------
y=-10/7x-3
make sure my work is good.
