x < -4

Answer

Dividing both sides by -3 and flipping the inequality sign gives x < -4.

Question 3

Which is the correct simplification of 5x + 3y - 2x + y?

Accepted Answer

3x + 4y

Answer

Combining like terms: (5x - 2x) + (3y + y) = 3x + 4y.

Question 4

If f(x) = 4x - 1, what is f(3)?

Accepted Answer

11

Answer

f(3) = 4(3) - 1 = 12 - 1 = 11.

Question 5

Which table of values represents a proportional relationship?

Accepted Answer

x: 1,2,3 | y: 2,4,6
