A person invested $3,600 in an account growing at a rate allowing the money to double every 13 years. How long, to the nearest tenth of a year would it take for the
value of the account to reach $11, 300?

20.8 years

Step-by-step explanation:

I got 13 years for a single (7,200), then I got the amount rounded to the nearest tenth and got the amount of years out of 13. Then, I added that into 13 to get 20.8!

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
