Evaluate the following expression using the values given: Find 3x - y - 3z if x = -2, y = 1, and z = -2. -13 -1 1 13

OpenStudy (anonymous):

what are -13 -1 1 13 these

OpenStudy (anonymous):

they are the multiple choice options only one is right

OpenStudy (anonymous):

Look : First get the numbers on the x&z&y OK ? For example : Find 2x-8 if X=15 we have 2(15)-8 30-8=22 Got it ?:)

OpenStudy (anonymous):

yup!

OpenStudy (anonymous):

and now answer this : find 3x if x=-2 answer :)

OpenStudy (anonymous):

-6

OpenStudy (anonymous):

Thank u:) 2th question : Find -y if y=1 answer :)

OpenStudy (anonymous):

I thinks its -13 for the whole thing

OpenStudy (anonymous):

No ... Look ... answer with that .write y in ( ) -( ) (just write y )

OpenStudy (anonymous):

-(y)

OpenStudy (anonymous):

I meant -(+1)=-1 OK ?

OpenStudy (anonymous):

You know : (-).(-)=+ So find -3z if z=-2

OpenStudy (anonymous):

6

OpenStudy (anonymous):

oK ! Now answer the first question u said again . If want help say :)

OpenStudy (anonymous):

13! a negative + a negative equals a positive!
