Answer:
For A, both equations have the same slope, but different y-intercepts. This means that they are parallel, and will never cross, meaning there is no solution.
For B, it's the same equation, meaning that they are always crossing (it's the same line!), so there are infinite solutions.
Answer:
<u>B. y</u>
Step-by-step explanation:
y is the variable because it is a letter representing a number.
The answer is 4 because when you add 2&2 you get 4
Answer:
Step-by-step explanation:
Given
Required
Find f(u)
To do this, we start by integrating the left-hand side
Using integration by parts, we have:
So, we have:
Differentiate
Integrate
So:
So, we have:
Integrate du using constant rule
Subtract c from both sides
Subtract u ln(u) from both sides
Rewrite as:
