Answer:
3
Step-by-step explanation:
3x+3-x+3=12
3x-x=12-3-3
2x=6
x=6/2
x=3
Answer:
Decreases
Step-by-step explanation:
We need to determine the integral of the DE;



We can solve this by integration by parts on the left side. We expand the fraction 1/P²:

let





Substitute u in:

Therefore the equation is:

We simplify:


As t increases to infinity P will decrease
Answer:
B
Step-by-step explanation:
A. these simply to 21 + 7x and 21 + 3x
- this one is incorrect because the 7x and 3x are different
B. these simplify to 10 + x and 10 + x
- this is the correct one since they are exactly the same
C. these simplify to 21x and 7x + 21
- these two are not the same because one expression has only a number with a variable but the other one has a number with a variable <em>and </em>another number
D. these simplify to
and 
- in subtraction, the order of the 3 and the x matters, so the equations are not the same
- example: 6 - 4 = 2 but 4 - 6 = -2
Answer: 2:3 and 12:18
Step-by-step explanation: Find the multiples of 6 and 9
Answer:
Step-by-step explanation:
In the table, you have an x column and a y column. To find values in the table, you choose your values of x and plug them in as your values of x in the equation, solving for y.
