Using the variable m for month
Club A: Club B:
19m+11 19m+11=18m+15 18m+15
-18m -18m
m+11= 15
-11 -11
m=4
Check 19(4)+11 = 87 18(4)+15= 87
total cost = 87
Answer:
no solutions
Step-by-step explanation:
Given the 2 equations
y = - 7x + 8 → (1)
y = - 7x - 8 → (2)
Substitute y = - 7x - 8 into (1)
- 7x - 8 = - 7x + 8 ( add 8 to both sides )
- 7x = - 7x + 16 (add 7x to both sides )
0 = 16 ← not possible
This indicates the system has no solutions
It is most likely the mean. Because the mean is the center of the data
Answer:
Step-by-step explanation:
We want to find:
First, using the quotient rule:
We can rewrite our expression as:
The logarithm of 1 is always 0. Therefore:
We can rewrite this as:
Using the product rule:
This is equivalent to:
Substitute:
