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
Complementary angles add up to 90 degrees.
The complement angle to 35 is:
90 - 35 = 55 degrees.
The answer is D.

Hi! So the equation would be y = 6x + 34 where y is the total amount.
You have 6x because the x shows how many days you are getting the 6 dollars.
You have 34 because that's how many dollars you started with. That is called the y-intercept.
For example, if I saved 6 dollars for ten days (which would be my x)--my equation would look like...
y = 6x + 34
y = 6(10) + 34
y = 60 + 34
y = 94
Hope this helps.
Hope you could get an idea from here.
