(85 + 75) * t = 448
160t = 448
t = 448/160
t = 2.8 hrs
Answer: 2.8 hrs
Thanks again you are VERY sweet and kind!

Answer:
100%
Step-by-step explanation:
An exponential equation with a growth rate can be expressed as:
where r is a positive number, and represents the growth rate.
In this case since the base of the exponent equals 2, that means r=1, since 1+1=2. This means it has a growth rate of 100%, which makes sense, since the base is 2, meaning it doubles or increases by 100% every time x increases by 1.
Answer:
The slope would be 5/2.
Step-by-step explanation:
Use the formula Y=mx+b. m always represents the slope and the b is the intercept. Therefore the slope of this would be 5/2.
