Accepted Answer

3x + 5y

Answer

Combine like terms: (4x − x) + (2y + 3y) = 3x + 5y.

Question 3

What is 15% of 200?

Accepted Answer

30

Answer

Each term is multiplied by 3, so 54 × 3 = 162.

Question 5

Which equation represents the line passing through (0, 3) with a slope of 2?

Accepted Answer

y = 2x + 3

Answer

Using slope-intercept form y = mx + b with m = 2 and b = 3 gives y = 2x + 3.
