Answer:
The answer is:
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟
❃Incase you also forgot, The is what the slope formula is ☟
➊ First: We are going to be solving for the slope.
➋Second: We find the y-intercept.
➌Third: Plug in.
x = 6
2x+3=15
2x=12
x=6
therefore,
6x+3=15
It be 81.
You have to take half of -18 which is -9, and square that, which is 81.
integral(x/(1+x^2)^2)dx
=(1/2)integral(2x/(1+x^2)^2)dx
=(1/2)[-1/(1+x^2)] +c
