Question

X1=10+15t x2=100-25t

Answer 1

X1=10+15t x2=100-25t

Answer 2

It seems like you've provided two equations with parameters "t" in them:

1. x1 = 10 + 15t
2. x2 = 100 - 25t

These equations represent linear functions of "t" where "t" is the independent variable, and "x1" and "x2" are the dependent variables. You can use these equations to describe how "x1" and "x2" change as "t" varies.

If you have a specific question or need to perform calculations using these equations, please provide more details or let me know what you would like to do with these equations, and I'd be happy to assist you further.
