Question

Which pair of terms contain opposite coefficients?

a. 7x and –7x
b. –7 and –7
c. 7 and –7
d. 7x and 7x

Answer 1

would it be 7x and -7x?

Answer 2

YES

Answer 3

coefficients are the values that are with variables

Answer 4

okay thank you. @xThatOneKidx , coefficients cannot have just the values?

Answer 5

yep. coefficients go with variables. If they are alone, then they are just constants. Like 2+4x=y. So 2 would be a constant. The coefficient of 4x is just 4. And for y it's 1. :)

Answer 6

hmmm

Answer 7

your teacher or on line system or whatever probably wants a) since the terms have opposite coefficients
but constants are coefficients too, so i would say c) is correct as well

Answer 8

True dat.

Answer 9

oh i see. but ill go with a).
