How do you solve x - 7 = 2?

1. Add 7 to both sides
2. Divide both sides by 7
3. Subtract 7 from both sides
4. Multiply both sides by 2

Which equation represents y = 2x + 1?

1. y - 1 = 2x
2. y - 2x = 1
3. 2x + y = 1
4. y + 2x = 1

What does 'x' equal in 5x = 20?

1. x = 4
2. x = 2
3. x = 5
4. x = 3

Which method solves x/3 = 5?

1. Divide both sides by 3
2. Add 3 to both sides
3. Subtract 3 from both sides
4. Multiply both sides by 3

What is the solution to 2x + 3 = 11?

1. x = 4
2. x = 2
3. x = 3
4. x = 5

3. A function with a single output
4. A linear function

What does the domain of a function represent?

1. The function's graph
2. All possible output values
3. All possible input values
4. The slope of the function

Which represents a linear function?

1. y = sin(x)
2. y = 2x + 3
3. y = log(x)
4. y = x^2

What is a function in mathematics?

1. A random set of numbers
