Which of the following is NOT a linear equation?
Answer: y = x² + 4
y = x² + 4 is a quadratic equation because it contains x raised to the second power.
Simplify: 3x + 2y - x + 5y
Answer: 2x + 7y
Combine like terms: (3x - x) + (2y + 5y) = 2x + 7y.
If f(x) = 3x - 2, what is f(4)?
Answer: 10
Substitute x = 4: f(4) = 3(4) - 2 = 12 - 2 = 10.
What is the y-intercept of the line y = 5x - 8?
Answer: -8
In slope-intercept form y = mx + b, the y-intercept b equals -8.
Solve: 2(x - 3) = 10
Answer: 8
Divide both sides by 2: x - 3 = 5, then add 3: x = 8.
Which inequality represents 'a number n is at least 15'?
Answer: n ≥ 15
'At least 15' means n is 15 or more, which is written as n ≥ 15.
A taxi charges a flat fee of $3 plus $2 per mile. Which equation represents the total cost C for m miles?
Answer: C = 2m + 3
The flat fee is $3 (starting value) and $2 per mile gives C = 2m + 3.
