A minute has 60 seconds, therefore we will deal with seconds now
And since we have it that the biker travels 5 feet every 0.5 seconds, lets multiply that by 2 to get the traveled distance per second to make it easier
5*2=10
Finally, multiply 10 feet by 60 seconds(1 minute)
= 600 feet
The answer is:
y = 3x - 8
Find b by plugging in the point (x,y) which is (3,1).
1= 3(3)+b
1= 9 + b
-8 = b

So your equation is

. You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now

You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's

right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be
0.36.
I hope I helped!
