Mr. Martin's math test, which is worth 100 points, has 29 problems. Each problem is worth either 5 points or 2
points.
Let x be the number of questions worth 5 points and let y
be the number of questions worth 2 points.
x + y = 29, 5x + 2y = 100

One expression below in undefined, and the other expression has a well defined value. which expression is undefined and explain why it has no value. which expression is defined? what is the value of that expression and how do you know? what is a different expression using a trig inverse function that is also undefined?

Can someone me and do the problem plz so i can understand it more better
