Answer:
The linear equation is y = 6 x + 9
The graph is attached down
Step-by-step explanation:
The given information:
The cost of 1st km is 9 Rs
The cost of every kilometer after the first is 6 Rs
x represents the number of km
y represents the total cost of x km
The form of the linear equation is
y = m x + b, where
- m is the slope of the line (rate of change)
- b is the y-intercept (initial value)
From the given information above
m = 6 Rs/km
b = 9 Rs
Substitute them in the form of the equation
y = 6 x + 9
The graph:
Answer:
2 hours
Step-by-step explanation:
add the time before and after adding 30 mins. (1 hour and 45 minutes/ 2 hours and 15 mins.) then divide by 2
Answer:
Step-by-step explanation:
Mean = ∑x/ N
91 = ∑x / 150
∑x = 150 * 91 = 13650
x= 6825 and y = 6825
Answer:
please provide table
there is no table in question
Direct proportion equations have the following form:
Where "k" is the Constant of proportionality.
In this case you know that "y" is directly proportional to "x" and when:
Having these values, you can substitute them into the equation and solve for "k":
So, substituting the value of "k" into the first equation shown above, you get that the equation that models the given relationship is:
Now, to find the value of "x", when the value of "y" is -24, you must substitute this value into the equation that models the relationship and then solve for "x". Then, you get:
Therefore, the answers are:
