Solve for x: 3(2x - 4) = 2(x + 6)
Answer: x = 6
Expanding gives 6x - 12 = 2x + 12, so 4x = 24 and x = 6.
Which of the following is a factor of x² - 7x + 12?
Answer: (x - 3)
x² - 7x + 12 = (x - 3)(x - 4), so (x - 3) is a factor.
If f(x) = 2x² - 3x + 1, what is f(-2)?
Answer: 15
f(-2) = 2(4) - 3(-2) + 1 = 8 + 6 + 1 = 15.
What is the slope of the line passing through (1, 3) and (4, 9)?
Answer: 2
Slope = (9 - 3)/(4 - 1) = 6/3 = 2.
Simplify: (3x²y)(4xy³)
Answer: 12x³y⁴
Multiply coefficients (3·4 = 12) and add exponents: x^(2+1) = x³ and y^(1+3) = y⁴.
Solve the inequality: -4x + 2 > 10
Answer: x < -2
-4x > 8 gives x < -2 (inequality flips when dividing by a negative).
What is the y-intercept of the line 5x - 2y = 10?
Answer: -5
Setting x = 0 gives -2y = 10, so y = -5.
