Let "per month" = m
The inequality is
1.5m + 4 ≥ 7
+ 4: Her hair right now is 4 cm long
1.5m: Her hair grows 1.5 per month (m)
≥ 7: She wants it to be at least 7 or more.
1.5m + 4 ≥ 7 is your answer
hope this helps

Answer:
Step-by-step explanation:
This graph is both linear and decreasing, as we move from left to right.
Answer:
Step-by-step explanation:
The exponential decay function is
where a is the initial value of the car, b is the rate of decay, and t is the time in years. Our rate of decay can also be written as (1 - r) where r is the depreciation in decimal form. Our equation looks like this:
which simplifies to
Now we can solve our problem for any number of years you'd like. We've been tasked to find the value of the car after 3 years, so:
which simplifies a bit to:
so
v(t) = 8043.57
