Question

Evaluate the polynomial 6x – y for x = –3 and y = 2.

Answer 1

where ever you see y sub in a 2 and where ever you see x sub in -3 so in this case we have 6(-3) - (2) = -18 - 2 = -20

Answer 2

put the given values in for the variables

6(-3) - (2)

6(-3) means 6 times -3, which is -18 so:

-18 -2 = -20

Answer 3

Ah ok! Thank you!!
