Answer:
(f -g)(2) = 14
Step-by-step explanation:
You can write the expression for the composite function as ...
(f -g)(x) = f(x) -g(x) = (3x² +1) -(1 -x)
(f -g)(x) = 3x² +x
Then for x = 2 ...
(f -g)(2) = 3(2²) +2
(f -g)(2) = 14
Answer:
The cost of one pass is 25$
Step-by-step explanation:
Call the cost of one of the passes, P. So we have
63 = 13 + 2P - subtract 13 from both sides
50 = 2P - divide both sides by 2
25 = P
So the cost of one pass = $25
Answer:
The number of teacher who joined the school is 20
Step-by-step explanation:
Teacher : Students = 1 : 16
Number of teachers = 1x
Number of students = 16x
16x = 1600
x = 1600/16
x = 100
Number of teachers at the beginning = 100
Now, after some teachers (let it be y) joining the school,
Teacher : students = 3:40
The number of teacher who joined the school is 20
