Answer: 7x + 261
Step-by-step explanation:
(5x + 252 + x + 5) + (x + 4)
5x + 252 + x + 5 + x + 4 (get rid of parenthesis)
7x + 261 (combine like terms)
Answer:
r≥2.5
it can't be < because the green dot is filled in
r is larger than 2.5 because the arrow goes to the right
We're looking for a scalar function 
such that 
. That is,
Integrate the first equation with respect to 
:
Differentiate with respect to 
:
Integrate with respect to :
So 
is indeed conservative with the scalar potential function
where 
is an arbitrary constant.
Answer:

Step-by-step explanation:
Given
4x - 8x ÷ 2
Under the rules of PEMDAS , division must be performed before subtraction.
Hence
4x - 8x ÷ 2 = 4x - 4x ← dividing - 8x by 2, then
4x - 4x = 0 ← correct answer
The domain is the value of x. In this case, -3≤x≤7
the range is the value of y. in this case, -1≤y≤9
this is not a function, because the same x value has two corresponding y values. For example, when x=5, y=0 or y=8
It IS a function if every x value has only one corresponding y value.
