Answer:
C = 6.75n + 50
Step-by-step explanation:
The equation for the cost of renting the party room can be written in the form;
C= mn+k ......i
Where C = cost
n = number of people
Substituting the 2 cases into the equation we have,
Case 1
117.5 = 10m + k ......1
Case 2
151.25 = 15m + k .....2
Subtracting eqn 1 from 2 we have
151.25 - 117.50 = 15m - 10m
5m = 33.75
m = 33.75/5 = 6.75
Substituting m = 6.75 into eqn 1, we have
117.50 = 10(6.75) + k
k = 117.5 - 67.50
k = 50
Therefore, rewriting the eqn i, we have
C = 6.75n + 50
The slopes are the same.
Example: y=2x+5 & y=2x+7
Answer:
3/7
Step-by-step explanation:
18/42=9/21=3/7 answer
66/55 in simplest form is 6/5. Because...
66÷ 11= 6
55÷ 11= 5
In slope intercept form it is y=2/3x-4
In point slope form it is 2/3x-y-4 :)
