Paige claims that the solution to the systems of linear equations y=2x-1 and -12x+3y=9 is (-2,-5). Which 3 methods could be used to verify Paige claim?

1) Plug in ordered pair into both equations and check if they are solutions

2) Graph both equations and see if they intercept at the point (-2,-5)

3) Solve the problem again

Those would be my 3 personal methods, not sure what your answer choices are though.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

560

hope this : )
