Answer:
x=63
x+15=78
Step-by-step explanation:
180-102=78
78-15=63
x=63
x+15=78
C is the answer. By only looking at the domain (the stuff on the right in the functions), you can see that the first equation has a hole at x=2, meaning it does not have a value here at x=2. When x<2, there are values for the 1st function. When x>2, there are values for the second function, as well as when x=2
1 (((m^(-1)) (m^5)) / (m^(-2)))^(-3) =1/m^18
18/20=K/110
20K= 110*18
20K= 1980
K= 99
Answer:
