1. Transpose the formula to make,” a” the subject. t =


2. Solve one system using one method.
2x – 2y = 5 3u – 2v = 2 2m + 4n = 6.8
4x + y = 1 5u + v = 4.2 5m – 2n = – 1
3. Solve quadratic equation by factorization, by completing squares.
4x2 – 12x + 8 = 0 3x2 + 5x – 2 = 0
4. A field has the form of right-angel trapezium ABCD. Angles of the base are B =
90 and A = 60. Side AD and diagonal BD are equal AD = BD = 16.4m. find the
area and circumference trapezium.
5. Solve the logarithmic and exponential equations.
log(x – 4)2 – log3= log(5 – 2x) 43x-2 = ex+3
6. In an experiment are measured the quantities Q and R. The results are on the
table below.

Q (units) 4 6.5 8 10 12.5


R (units) 24.3 45.3 62.7 91.5 136
It is thought that “R” is related to “Q” by the law R = aQ + b, where a and b
