8 A quiz contains 25 questions with a total score of 150 marks. The quiz consists of two sections where Section A has multiple choice questions which award 3 marks each
and Section B has short structured questions which award 8 marks each.

(a) Write two simultaneous linear equations to represent the above information.

(b) Hence, by using the matrix method, calculate the number of questions in Section A
and the number of questions in Section B.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

the answer would be 0.54
