Answer:
See below.
Step-by-step explanation:
There is an infinite n umber of systems of equations that has (1, 4) as its solution. Are you given choices? Try x = 1 and y = 4 in each equation of the choices. The set of two equations that are true when those values of x and y are used is the answer.
Answer:

Step-by-step explanation:
Hey there!
I'm assuming your expression is actually

. If it's not, let me know and I'll be happy to help you out further.
If x were equal to –9, your expression would be undefined. If you solve it with this value plugged in for x, you will get the following:





You can't divide anything by zero. This expression would be undefined if x were –9 since it makes the denominator zero. Therefore, x ≠ –9.
Hope this helped you out! :-)
The area of the big circle is 415.48 and the smaller one is 59.69 so divide 59.69 by that number and multiply by 100 then do 100- that number(14.37) to get 85.63%
