Question groups

Group 10 questions

1.
Ready to use

This question tests the student's ability to solve simple linear equations by elimination. Part a) involves only having to manipulate one equation in order to solve, and part b) involves having to manipulate both equations in order to solve.
2.
Ready to use

Given a randomised rational function select the possible ways of writing the domain of the function.
3.

6.
Ready to use

Rearrange some expressions involving logarithms by applying the relation $\log_b(a) = c \iff a = b^c$ .
7.
Ready to use

Given a sum of logs, all numbers are integers, $\log_b(a_1)+\alpha\log_b(a_2)+\beta\log_b(a_3)$ write as $\log_b(a)$ for some fraction $a$ . Also calculate to 3 decimal places $\log_b(a)$ .
8.
