What is the value of 3x + 2 when x = 2?
8
6
10
7
Substitute x = 2 into the expression: 3(2) + 2 equals 6 + 2, which is 8. This is a straightforward substitution problem.
Solve for x: x - 5 = 0.
-5
10
0
5
Adding 5 to both sides of the equation gives x = 5. This demonstrates a basic method for solving a linear equation.
In the expression 4x + 7, what is the coefficient of x?
4
11
7
1
The coefficient is the number multiplying the variable. In 4x + 7, the coefficient of x is 4.
If y = 3, what is the value of 2y - 1?
7
4
5
6
Substitute y = 3 into 2y - 1 to get 2(3) - 1, which simplifies to 6 - 1 and equals 5. This reinforces the idea of substitution in algebraic expressions.
Simplify: 2(3 + 4).
12
14
10
16
First add the numbers inside the parentheses: 3 + 4 equals 7, then multiply by 2 to get 14. This is a basic application of the distributive property.
Solve for x: 2x + 3 = 11.
4
8
5
6
Subtract 3 from both sides to obtain 2x = 8, then divide both sides by 2 to find x = 4. This exercise reinforces the steps needed to isolate the variable.
Simplify: 3x + 2x - 5.
6x - 5
5x - 1
5x - 5
5x + 5
Combine like terms 3x and 2x to get 5x, and then subtract 5 to yield 5x - 5. This question focuses on proper term grouping and simplification.
Solve for x: 3(x - 2) = 12.
6
5
4
8
Divide both sides by 3 to get x - 2 = 4, then add 2 to both sides to obtain x = 6. This tests the understanding of dissolving parentheses and basic equation solving.
Simplify: 4(2 + x) - x.
6 + 3x
8 + 4x
8 - 3x
8 + 3x
Distribute 4 to get 8 + 4x, then subtract x to combine like terms resulting in 8 + 3x. This problem applies both the distributive property and combining like terms.
Solve: 5x - 7 = 2x + 8.
5
7
3
4
Subtract 2x from both sides to get 3x - 7 = 8, then add 7 and divide by 3 to obtain x = 5. This tests the ability to balance and simplify a linear equation.
What is the slope of the line passing through the points (1, 2) and (3, 8)?
6
4
2
3
Using the slope formula (y2 - y1)/(x2 - x1), substitute the given points to find (8 - 2) / (3 - 1) = 6/2 = 3. This reinforces calculating slopes in coordinate geometry.
For the equation 2(x + 3) = x + 9, what is the value of x?
4
3
6
2
Expand to get 2x + 6 = x + 9; by subtracting x from both sides, you get x + 6 = 9, hence x = 3. This problem applies distribution and isolation of the variable.
Simplify: 2x + 3 - x + 4.
x + 1
x - 7
3x + 7
x + 7
Combine like terms: 2x - x gives x, and 3 + 4 equals 7, leading to the simplified expression x + 7. This exercise reinforces combining like terms.
Which expression is equivalent to 3(x + 4)?
3x + 7
3x + 4
x + 12
3x + 12
Use the distributive property by multiplying 3 with both x and 4, which gives 3x + 12. This confirms an understanding of distribution.
Solve the inequality: 2x - 5 < 7.
x > 6
x > -6
x < -6
x < 6
Add 5 to each side yielding 2x < 12, then divide by 2 to get x < 6. This problem tests an understanding of solving basic inequalities.
Solve for x: (x/2) + 3 = 7.
4
10
7
8
Subtracting 3 from both sides gives x/2 = 4 and multiplying both sides by 2 results in x = 8. This problem emphasizes working with fractions in equations.
Solve: 4(x - 2) + 2(3x + 1) = 20.
13/5
5
2
3
First, distribute to get 4x - 8 + 6x + 2, which simplifies to 10x - 6 = 20. Solving by adding 6 and then dividing by 10 results in x = 26/10 or 13/5.
If f(x) = 2x² - 3x + 1, what is f(2)?
4
6
3
5
Substitute x = 2 into the function: 2(2²) - 3(2) + 1 = 8 - 6 + 1, which simplifies to 3. This problem tests the evaluation of a quadratic function.
Solve for x: 5(x + 2) - 3(2x - 4) = 2x + 10.
2
5
6
4
Expanding the expressions gives 5x + 10 - 6x + 12, which simplifies to -x + 22. Setting this equal to 2x + 10 and solving yields x = 4. This problem reinforces the distributive property and combining like terms.
Solve for y in terms of x: 3y + 2x = 12.
y = (12 + 2x)/3
y = (2x - 12)/3
y = 4 + (2/3)x
y = 4 - (2/3)x
Subtract 2x from both sides to get 3y = 12 - 2x and then divide by 3 to isolate y, resulting in y = 4 - (2/3)x. This question tests the ability to rearrange an equation to solve for one variable.
