F(x) = x
f(x+1) = x+1.
for x = 0, f(x+1) = 1 (this is the value of y intercept).
The only graph that has 1 as y intercept is the second one
Answer:
60 students passed, and 75 appeared in examination.
Step-by-step explanation:
Let's say s is the total number of students and p is the number of students who passed.
80% of the students passed, so:
0.8 s = p
If there were 10 less passers, and 15 less students (5 less failures), then the ratio of passers to failures would be 5/1.
(p − 10) / (s − p − 5) = 5 / 1
Simplify the second equation:
p − 10 = 5 (s − p − 5)
p − 10 = 5s − 5p − 25
6p = 5s − 15
Substitute the first equation.
6 (0.8 s) = 5s − 15
4.8 s = 5s − 15
0.2 s = 15
s = 75
p = 0.8 s
p = 60

Answer:
y = 18
Step-by-step explanation:
72 is 15% of 480. if you divide 72 by 480 it gives you .15 and then you mutiply the .15 by 100
