Question

Consider the expression 7x2 - 4 - 9x. What is the coefficient of x?

A) -4
B) 7
C) -9
D) 9

Answer 1

D) 9

Explanation:

7 x 2 - 4 - 9x

14 - 4 - 9x

10 - 9x

You could easily see at first that the coefficient of x is 9 because the coefficient is the number that is before the variable, but you can also do the whole process.
