Solve for x: 2x + 3 = 7.
x = 3
x = 1
x = 4
x = 2
Subtract 3 from both sides to get 2x = 4, then divide by 2 to obtain x = 2. This method is a standard approach to solving a simple linear equation.
What is the value of 3²?
8
6
12
9
3² means 3 multiplied by itself, which equals 9. This is one of the basic properties of exponents.
Simplify the expression: 1/2 + 1/3.
1/6
1
5/6
2/3
Find a common denominator (6) to combine the fractions: (3 + 2)/6 equals 5/6. This shows the proper addition of fractions.
Which of the following numbers is a prime number?
6
7
4
9
A prime number has only two distinct positive divisors: 1 and itself. Among the options, 7 meets this criterion.
What is the result of 5 minus 3?
4
3
1
2
Subtracting 3 from 5 gives 2. This is a basic arithmetic operation expected at the Grade 9 level.
Solve for x: 3x - 5 = 10.
x = 4
x = 6
x = 3
x = 5
Add 5 to both sides to obtain 3x = 15, then divide by 3 to get x = 5. This step-by-step process illustrates solving a linear equation.
Solve the equation: 2(x - 3) = 10.
x = 8
x = 9
x = 5
x = 7
Divide both sides by 2 to get x - 3 = 5, then add 3 to both sides to obtain x = 8. This method uses basic algebraic manipulation.
What is the slope of the line given by the equation y = 2x + 1?
-2
2
-1
1
In the slope-intercept form y = mx + b, the coefficient m is the slope. Here m is 2, so the slope of the line is 2.
Find the y-intercept of the line represented by 3x + 4y = 12.
4
0
3
1
Set x = 0 in the given equation to obtain 4y = 12, which simplifies to y = 3. Thus, the y-intercept is 3.
Factor the quadratic expression: x² - 5x + 6.
(x - 1)(x - 6)
(x + 2)(x + 3)
(x - 2)(x - 3)
(x - 3)(x + 2)
Look for two numbers that multiply to 6 and add up to -5. The numbers -2 and -3 satisfy these conditions, so the factorization is (x - 2)(x - 3).
Solve the system of equations: x + y = 7 and x - y = 3.
x = 3, y = 4
x = 5, y = 2
x = 2, y = 5
x = 4, y = 3
Adding the two equations eliminates y, yielding 2x = 10, so x = 5. Substituting back into either equation gives y = 2.
If 25% of a number is 10, what is the original number?
40
50
20
30
Since 25% represents one-quarter, multiplying 10 by 4 yields the original number, which is 40. This is a direct application of percentage-to-fraction conversion.
What is the value of √49?
6
9
7
8
The square root of 49 is 7, because 7 multiplied by 7 equals 49. This is a fundamental property of square roots.
Simplify the expression: 3(2x + 4) - 2(x - 1).
6x + 10
2x + 14
4x + 10
4x + 14
Distribute to get 6x + 12 from the first term and -2x + 2 from the second. Combining like terms results in 4x + 14.
Calculate the value of (2³) × (2²).
32
8
64
16
When multiplying powers with the same base, add the exponents: 2^(3+2) equals 2❵, which is 32. This demonstrates the laws of exponents.
Find the sum of the solutions of the equation: x² - 4x - 5 = 0.
4
-4
5
0
Using the quadratic formula, the sum of the roots of ax² + bx + c = 0 is given by -b/a. Here, -(-4)/1 equals 4.
Solve the system of equations: 2x + 3y = 12 and 4x - y = 5.
x = 27/14, y = 19/7
x = 27/14, y = 27/14
x = 3, y = 2
x = 2, y = 4
Express y from the second equation as y = 4x - 5 and substitute into the first equation. Solving the resulting equation gives x = 27/14 and subsequently y = 19/7.
For the function f(x) = 2x + 3, what is the value of f(5)?
10
15
11
13
Substitute x = 5 into the function: f(5) = 2(5) + 3 = 13. This direct substitution checks the understanding of function evaluation.
A triangle has an area of 20 and a base length of 8. What is its height?
6
5
4
10
Using the formula for the area of a triangle, (1/2) × base × height = area, substitute the given values to get 4 × height = 20. Solving yields a height of 5.
A rectangle's length is twice its width and its perimeter is 36. What is the area of the rectangle?
60
72
84
80
Let the width be w; then the length is 2w. The perimeter is 2(w + 2w) = 6w = 36, which gives w = 6 and length = 12. Multiplying these dimensions yields an area of 72.
