If 2x = 3 + 5i, then the value of 2x3 + 2x2 - 7x +72 is

1) 4

2) -4

3) 8

4) -8  

If the function   is written in the form  , then the values of a and c are

4. If y is defined implicitly by the equation ety + y = 2 + (1 + 1)2 then the value of die evaluated at (0, 2) is (A)e-1 (B) 1/2 (C)1 (D) 2 ((E) 0]

1 h 3] 3. Suppose that a system of equations has the augmented matrix TIX0 -5h – 10k - 15 If the system is inconsistent, then the values of h and k must be: (b) h= 2, k = 15 (c) h -2, k = 15 (d) h = -2, k = 15 (a) h= -2, k = 15 (e) h + -2, k #15
