Question

1. Examine the expression 5x + 9 - 2x - 7y.
a. How many terms are in the expression?
b. What is the coefficient of the y term?
c. Write the expression in simplified form.

Answer 1

Answer:

a. 4

b. -7

c. -7y+3x+9

Step-by-step explanation:

A. Okay well 5x, 9, -2x, and -7y are the 4 terms.

B. The coefficient (meaning the number attached to the y) is -7

C. Simplified would be finding the common variables; 5x and -2x. Subtract and you get 3x. You can't combine any more of your terms so you are left with -7y+3x+9
