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:
negative
slope= -1/4
Step-by-step explanation:
Answer:
Option C) c+9 is correct
The sum of the number of cars and 9=c+9 is correct algebraic expression representation for given phrase
Step-by-step explanation:
Given that c=the number of cars in a parking lot.
The phrase given is "the sum of the number of cars and 9"
To find the algebraic expression which represents the given phrase :
The algebraic expression to the given phrase is c+9
That is option C) c+9 is correct
The sum of the number of cars and 9=c+9 is correct algebraic expression representation for given phrase
Answer:
There are 25 chickens and 20 rabbits
Step-by-step explanation:
Let
x-----> the number of chickens
y ----> the number of rabbits
Remember that
1 chicken has two legs
1 rabbit has four legs
so
2x+4y=130 -------> equation A
x=y+5 -----> equation B
Substitute equation B in equation A and solve for y
2(y+5)+4y=130
2y+10+4y=130
6y=120
y=20 rabbits
Find the value of x
x=y+5
x=20+5=25 chickens
