-2 because in the second equation it is : 2x. If you multiply x in the first equation by -2 it will cancel out 2x in the second equation. -2x cancels out 2x. -2x+2x=0
Answer:
C
Step-by-step explanation:
when graphed c is the only straight line.
Answer:
Option B) -9 is correct
The evaluated given expression when x=-3 is 2x+x=-9
Step-by-step explanation:
Given expression is 2x+x
Now to evalute the given expression when x=-3 as below :
2x+x when x=-3
That is put x=-3 in the given expression we get
2x+x=2(-3)+(-3)
=-6-3
=-9 ( adding the like terms here )
Therefore 2x+x=-9
The evaluated given expression when x=-3 is 2x+x=-9
Option B) -9 is correct
that meen EVALUATE (y) at x=4
y=1
