Colorful paper art promoting a Chapter 2 Brain Boost practice quiz for high school algebra students.

Solve for x: 2x + 3 = 11.
x = 4
x = 5
x = 3
x = 6
Subtracting 3 from both sides yields 2x = 8, and dividing both sides by 2 gives x = 4. This is a straightforward linear equation.
Solve for x: x - 5 = 7.
x = 12
x = 2
x = 5
x = -2
Adding 5 to both sides yields x = 12, which is the correct solution. This problem helps in building basic equation-solving skills.
Find the slope of the line passing through the points (0, 2) and (2, 6).
2
4

1
The slope is calculated as (6 - 2) / (2 - 0) = 4/2 = 2. This question reinforces the concept of slope using two points.
Simplify: 3(2 + x) when x = 4.

Substituting x = 4 produces 3(2 + 4) = 3(6) = 18. This tests both substitution and basic multiplication skills.
Factor the quadratic: x² + 5x + 6.
(x + 2)(x + 3)
(x - 2)(x - 3)
(x + 1)(x + 6)
(x + 3)(x + 4)
The factors of 6 that add to 5 are 2 and 3, so the quadratic factors as (x + 2)(x + 3). This reinforces basic factoring techniques.
Solve the equation: 3(x - 2) = 2x + 1.
x = 7
x = 5
x = -7
x = -5
Expanding the left side gives 3x - 6 = 2x + 1, and isolating x leads to x = 7. This question reinforces distribution and solving simple linear equations.
Determine the x-intercept of the line 4x + 2y = 8.
2
4
-2
-4
Setting y to 0 in the equation 4x + 2y = 8 results in 4x = 8, so x = 2. This tests the concept of intercepts in a linear equation.
Solve the inequality: 2x - 3 > 5.
x > 4
x ≥ 4
x < 4
x ≤ 4
Adding 3 to both sides gives 2x > 8, and dividing by 2 results in x > 4. This problem focuses on solving linear inequalities.
Find the value of y for the function f(x) = 2x² - 3x + 1 when x = 3.

13
9
Substituting x = 3 into the function gives 2(9) - 3(3) + 1 = 18 - 9 + 1 = 10. This question tests evaluation of a quadratic function.
Which property justifies that a + b = b + a?
Commutative Property
Associative Property
Distributive Property
Identity Property
The commutative property of addition states that changing the order of the addends does not affect the sum. This is a foundational algebraic property.
Solve for x: 5/(x - 2) = 1.
7
3
5
2
Multiplying both sides by (x - 2) results in 5 = x - 2; adding 2 to both sides gives x = 7. This problem emphasizes solving rational equations.
If f(x) = 3x + 2, what is f(4)?
14
12
16
10
Substitute x = 4 into the function to get 3(4) + 2 = 12 + 2 = 14. This reinforces the concept of function evaluation.
Simplify the expression: (2x²y)/(4xy²).
x/(2y)
x/(2y²)
x²/(2y)
x/(4y)
Cancel the common factors: divide numerator and denominator by 2xy to simplify the expression to x/(2y). This question tests the simplification of algebraic fractions.
Solve the equation: x² - 9 = 0.
x = 3 or x = -3
x = 3
x = -3
x = 9
The expression factors as (x - 3)(x + 3) = 0, yielding solutions x = 3 and x = -3. This reinforces quadratic factoring techniques.
Simplify: 2(3x - 4) + 4(x + 2).
10x
7x
12x
2x
Distribute to obtain 6x - 8 + 4x + 8, which simplifies to 10x after combining like terms. This tests the use of the distributive property and combining like terms.
Solve the quadratic equation: x² - 5x + 6 = 0.
x = 2 or x = 3
x = -2 or x = -3
x = 2
x = 3
Factoring the quadratic as (x - 2)(x - 3) = 0 yields solutions x = 2 and x = 3. This problem reinforces understanding of quadratic factoring.
For the function f(x) = (x² - 4)/(x - 2), determine f(3).
5
1
3
7
Factor the numerator as (x - 2)(x + 2) so that the function simplifies to f(x) = x + 2 (for x ≠ 2). Thus, f(3) = 3 + 2 = 5. This tests both factoring and function evaluation.
If f(x) = ax + b and f(2) = 5 and f(5) = 11, find the value of a.
2
3
4
1
Setting up the equations: 2a + b = 5 and 5a + b = 11. Subtracting yields 3a = 6, hence a = 2. This involves solving a system of linear equations from function values.
Determine the solution set for the inequality: -3(x - 2) ≤ 9.
x ≥ -1
x ≤ -1
x > -1
x < -1
Distributing gives -3x + 6 ≤ 9. Subtracting 6 results in -3x ≤ 3, and dividing by -3 (with reversal of the inequality) gives x ≥ -1. This problem tests understanding of inequality rules.
Solve the system of equations: 2x + 3y = 12 and x - y = 1.
x = 3, y = 2
x = 2, y = 3
x = 3, y = -2
x = -3, y = 2
Using substitution from x - y = 1 (i.e., x = y + 1) in the first equation leads to 2(y + 1) + 3y = 12, resulting in y = 2 and then x = 3. This problem reinforces solving systems of equations using substitution.

  8. Understand the discriminant - The discriminant (b² - 4ac) is like a fortune-teller for quadratics: positive means two real roots, zero means one golden double root, and negative summons complex pairings. Know it to predict your equation's fate! OpenStax: Discriminant Details
  9. Solve absolute value equations - Absolute value equations split into two scenarios - one positive and one negative - like choosing different adventure paths. Solve each scenario separately to capture all possible solutions. OpenStax: Absolute Value Tips
  10. Interpret and solve linear inequalities - Inequalities behave like traffic signs: watch for > or <, and if you multiply or divide by a negative number, reverse that sign! Follow these rules to navigate solutions safely. OpenStax: Inequality Guide
