Step-by-step explanation:
for f(x) and g(x) to be inverse,
f(g(x))=g(f(x))=x
Answer:
x = 1.5
Step-by-step explanation:
We need a value of x that would result in 2x+9 = 12
2x+9 = 12
2x = 12 - 9
2x = 3
x = 3/2 or 1.5
====
CHECK
Does 2x+9 = 12 when x = 1.5?
2x+9 = 12
2(1.5)+9 = 12
3 + 9 = 12 YES
Answer:
m = -1, c = 2
Step-by-step explanation:
if A ( 3, 5) and B (1, 4) lie on the graph of the line mx + cy = 7, then their coordinates satisfy the equation of the line:
A: 
B: 
From the second equation:

Substitute it into the first equation:
