Find out which of the transformations in Exercises 1 through 50 are linear. For those that are linear, determine whether they are isomorphisms.
1. T(M) = M + 12 from R2x2 to R2x2
2. T(M) = 7M from R2x2 to R2x2
3. T(M) = (sum of the diagonal entries of M) from R2x2 to R
4. T(M) = det(M) from R2x2 to R
5. T(M) = M2 from R2x2 to R2x2
6. T(M) = M from R2x2 to R2x2 6. T(M)= M [} 21 from R2X2 to R2x2
7. T (M) = [; 2) M from R2x2 to R2x2
8. T(m) = M [} £] m from R2^2 to R2x2
9. TM) = s-!ms, where s = [4), from R2«2 10
10. T(m) = PMP-t, where P = [} } ], from R2x2 10 R2x2 R2x2

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
