Answer:

Step-by-step explanation:
Let
x -----> the number of hours
y ----> the total cost to rent a bike in dollars
we know that
The equation of the line in slope intercept form is equal to

where
m is the slope or the unit rate of the linear equation
b is the y-intercept or the initial value
In this problem we have
The unit rate or slope is equal to

The y-intercept (value of y when the value of x is equal to zero) is equal to
----> (fee charge)
substitute the values

Answer: 24 plants
Step-by-step explanation:
1000 is not a perfect square.
31^2 < 1000 < 32^2
Required no. of trees = 32^2 − 1000
= 1024 − 1000
= 24
