-11 3
-3 4
3/7
3/4
11 3
Correct answer is A
-1-(-3)/-2-(-0.5) = 2/-1.5 = 20/-15 = -113
If x is positive, for what range of values of x is 4 + 3x < 10?
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
