We start with:
y=2x-15
y=5x
Now, we have a perfectly set-up variable we can get rid of: <em>y.</em>
But we need to make either the top or bottom equation negative, so for simplicity, let's make the bottom one negative.
y=2x-15
(-y)=(-5x)
Now simplify.
-3x-15=0
Add 3x on both sides.
3x=15
Divide by 3 on both sides.
x=5
Answer: 81
since it's the 4th power then you do 3x3x3x3= 81
Step-by-step explanation:
Answer:
x+y>1
Step-by-step explanation:
Answer:
58
Step-by-step explanation:
42+4(6-2) =
42+4(4) =
42+16 = <u>58</u>
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.
