Question

What are the coefficients in this expression? 2x +9y+(-4) Select all that apply.

Answer 1

Answer: A and B

Step-by-step explanation:

Coefficient is the number or term that came before a variable.

If you can't understand this, I will provide some examples.

• Coefficient in 3x is 3, 3 came before x which is a variable

-------------------------------------------------------------------

2x + 9y + (-4)

2x: coefficient is 2

9y: coefficient is 9

-4: no coefficient, it is just a constant

Answer 2

A) 2 and B) 9
Coefficients are the numbers in front of a variable. The x and y wouldn’t be considered coefficients.
