Consider the expression 7x2 - 4 - 9x. what is the coefficient of x?
a) -4
b) 7
c) -9
d) 9

D) 9

Step-by-step 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.

Hope this was helpful :)
