Answer:
y= 4.3(4)^x
Step-by-step explanation:
I went to the Desmos Graphing calculator
I then inserted a table and added the two points you gave me to it
I then performed exponential regression to find the rate of change and y-intercept.
I then took the the two values and wrote the equation
A=y-intercept
B=rate
Determinati x € R astef incat 1 supra 9= 16
It would be 15,20,29.... if you use pythagorean the rest dont work
Answer:
It will take 7 hours for car B to catch up to Car A.
Step-by-step explanation:
So if you write the the two equations out:

You'll want to assume that x is how many hours and y is how many km.
The reason car B has, -140, is because car A is in front of it by two hours and in those two hours it reached 140km. Meaning that Car B is starting at 140 km behind Car A.
If you graph these two equations out you'll realize that they intersect at the point (7, 490). Meaning that Car B caught up with Car A after 7 hours and both cars had traveled 490km.
