Solve for x: 2x + 3 = 11.
x = 8
x = 4
x = 7
x = 3
Subtracting 3 from both sides gives 2x = 8. Dividing both sides by 2 yields x = 4.
Solve for x: x/4 = 5.
x = -20
x = 1
x = 20
x = 9
Multiplying both sides of the equation by 4 isolates x. So x = 4 Ã- 5 = 20.
What is f(3) if f(x) = 2x + 1?
5
7
6
3
Substitute x = 3 into the function to get f(3) = 2(3) + 1 = 7. This direct substitution isolates the variable for evaluation.
Find the next term in the arithmetic sequence: 5, 8, 11, ...
15
14
12
13
The sequence increases by 3 each term, so adding 3 to the last term 11 gives 14. Recognizing the constant difference confirms 14 as the next term.
Which operation isolates x in 5x - 2 = 13 first?
Multiply by 5, then add 2
Add 2, then divide by 5
Divide by 5, then subtract 2
Subtract 5, then divide by 2
We first undo the subtraction by adding 2 to both sides, giving 5x = 15. Then dividing by 5 isolates x = 3.
Solve for x: 3(x - 2) = 9.
x = 1
x = 5
x = -5
x = 3
Expanding the expression gives 3x - 6 = 9. Adding 6 and then dividing by 3 gives x = 5.
What are the roots of the equation x^2 - 5x + 6 = 0?
x = -2 and x = -3
x = 3 and x = -2
x = 2 and x = 3
x = 1 and x = 6
The quadratic factors as (x - 2)(x - 3) = 0, so the solutions are x = 2 and x = 3. Setting each factor to zero isolates the roots.
A sequence follows the rule a_n = n^2 + 1. What is the fifth term?
20
24
25
26
Plugging n = 5 into the formula gives 5^2 + 1 = 26. This follows directly from substituting the index into the rule.
What is f(g(2)) when f(x) = x + 3 and g(x) = 2x?
4
5
8
7
First compute g(2) = 4, then substitute into f to get f(4) = 7. This nested evaluation combines both function rules.
Which method is most efficient to solve the system: 2x + 3y = 6 and x = 2y - 1?
Elimination
Graphing
Substitution
Quadratic formula
Since x is already isolated in the second equation, substituting 2y - 1 into the first equation is fastest. This avoids additional elimination steps.
If P = 2(l + w) and P = 20 when l - w = 2, what are the values of l and w?
l = 7 and w = 3
l = 6 and w = 4
l = 5 and w = 5
l = 4 and w = 6
From the perimeter equation l + w = 10 and the difference equation l - w = 2, adding them gives 2l = 12 so l = 6. Substituting back yields w = 4.
Which expression simplifies 4(x + 2) - 3x?
x - 8
x + 8
8x
x + 2
Distribute 4 to get 4x + 8, then subtract 3x to obtain x + 8. This combines like terms correctly.
The quadratic function h(x) = x^2 - 4x + 3 has its vertex at which point?
(2, -1)
(1, -2)
(4, 3)
(-2, 1)
The vertex formula x = -b/(2a) gives x = 4/2 = 2, and h(2) = 2^2 - 4·2 + 3 = -1. Therefore, the vertex is at (2, -1).
Given the sequence 3, 8, 15, 24, ..., where the differences increase by 2 each time, what is the sixth term?
35
50
48
42
Differences are 5, 7, 9, 11, 13, so the fifth term is 35 and the sixth term adds 13 to 35 giving 48. Recognizing this quadratic difference pattern leads to 48.
Which function rule models doubling the input then adding 5?
f(x) = x^2 + 5
f(x) = (x + 5)/2
f(x) = 2x + 5
f(x) = 2(x + 5)
Applying the doubling as 2x and then adding 5 yields the rule f(x) = 2x + 5. This matches the described operation order.
Solve for x: x^2 - 3x - 10 = 0.
x = -2 or x = -5
x = 5 or x = -2
x = -5 or x = 2
x = 2 or x = 5
Factoring gives (x - 5)(x + 2) = 0, so x = 5 or x = -2. This finds both roots of the equation.
Solve the system of equations x + y = 5 and x - y = 1.
x = 4 and y = 1
x = 3 and y = 2
x = 1 and y = 4
x = 2 and y = 3
Adding the two equations gives 2x = 6 so x = 3, then substituting back yields y = 2. This elimination approach quickly finds both variables.
What is the vertex form of the quadratic function f(x) = x^2 + 6x + 5?
f(x) = (x - 3)^2 + 4
f(x) = (x - 6)^2 - 5
f(x) = (x + 6)^2 + 5
f(x) = (x + 3)^2 - 4
Completing the square gives f(x) = (x + 3)^2 - 4, revealing the vertex at (-3, -4). This is the standard method to convert to vertex form.
For what value of k does the quadratic equation x^2 + kx + 9 = 0 have exactly one real root?
k = 0
k = 3
k = 9
k = 6 or k = -6
A single real root occurs when the discriminant is zero, so k^2 - 36 = 0 gives k = ±6. This condition yields a repeated root.
What is the domain of the function f(x) = 1/(x - 2)?
All real numbers
x > 2
All real numbers except x = 2
x < 2
The denominator cannot be zero, so x = 2 is excluded. Therefore, the domain is all real numbers except 2.
