-x+5y=-17 And x-3y=7 solve the system of two linear equations

What is the domain of the given function? {(3,-2), (6, 1), (-1, 4), (5,9), (-4, 0); o {x | x= -4,-1, 3, 5, 6} o {yl y = -2,0, 1,4,9} o {x|x = -4,-2, -1,0, 1, 3, 4, 5, 6, 9} o y y = 4,-2, -1, 0, 1, 3, 4, 5, 6, 9}

Will give a: 122 b: 90 c: 48 d: 180

Solve 4 ln x=2ln25 a) x=5 b) x=25 c) x=625
