0 < x < 2
x < 2
1 < x < 2
0 < x < 4 3 4
0 > x > 2
Correct answer is B
4 + 3x < 10
3x < 10 - 4
3x < 6
x < 2
For what value of x is the expression \(\frac{x^2 + 15x + 50}{x - 5}\) not defined ?
-10
-5
0
5
10
Correct answer is D
\(\frac{x^2 + 15x + 50}{x - 5}\)
It is undefined when x - 5 = 0.
That is at x = 5.
If 8x- 4 = 6x- 10, find the value of 5x,
-35
-15
-3
3
7
Correct answer is B
8x - 4 = 6x - 10 8x - 6x = -10 + 4 2x = -6 x = -3 ∴ 5x = 5(-3) = -15

Given that 2p - m = 6 and 2p + 4m = 1, find the value of (4p + 3m).
1

9
Correct answer is D
2p - m = 6 ... (i) 2p + 4m = 1 ... (ii) From (i), m = 2p - 6. 2p + 4(2p - 6) = 1 2p + 8p - 24 = 1 10p = 1 + 24 = 25 p = 2.5 m = 2(2.5) - 6 = 5 - 6 = -1 ∴ 4p + 3m = 4(2.5) + 3(-1) = 10 - 3 = 7
