Solve for x: (x/3) + 4 = 7
Answer: x = 9
Subtracting 4 gives x/3 = 3, then multiplying by 3 gives x = 9.
What is the y-intercept of the line 5x - 2y = 10?
Answer: (0, -5)
Setting x = 0 gives -2y = 10, so y = -5, making the y-intercept (0, -5).
If f(x) = 3x - 2, what is f(4)?
Answer: 10
f(4) = 3(4) - 2 = 12 - 2 = 10.
Which value of x satisfies |2x - 6| = 8?
Answer: x = 7 or x = -1
2x - 6 = 8 gives x = 7, and 2x - 6 = -8 gives x = -1.
Two consecutive integers have a sum of 53. What is the larger integer?
Answer: 27
If n and n+1 are consecutive integers, then 2n + 1 = 53, giving n = 26 and n+1 = 27.
What is the x-intercept of the line y = -3x + 9?
Answer: (3, 0)
Setting y = 0 gives -3x + 9 = 0, so x = 3, making the x-intercept (3, 0).
