Answer:
Step-by-step explanation:
The number of students in each bus = s.
It is given that,
6 students traveled by car and the rest traveled in 11 buses.
So, the total number of students traveled = 11s + 6.
Since, the least number of students traveled is 450.
Thus, we get the inequality representing the situation is,
Answer:
(a)
(b)
Step-by-step explanation:
(a) From inspection of the graph, the x-intercepts (where ) are at
and
.
Therefore where
is some constant
The y-intercept is at (0, -8)
Expanding the equation:
Therefore, -8a is the y-intercept
Comparing y-intercepts: -8 = -8a ⇒ a = 1
Substituting a = 1, the final equation in standard form is:

(b) From inspection of the graph, the x-intercepts (where ) are at
and
.
Therefore where
is some constant
The y-intercept is at (0, -6)
Expanding the equation:
Therefore, 12a is the y-intercept
Comparing y-intercepts:
Substituting found value of a into the equation:
