Solve the following quadratic-linear system of equations.

D.

Step-by-step explanation:

The given quadratic linear system of equations is:

.

We equate the two equations to obtain;

.

Rewrite in the general quadratic form to get;

.

Observe that the expression on the left hand side is a perfect quadratic trinomial.

.

.

Substitute into either equation (1) or (2) to get;

The solution is .

Therefore the correct answer is D

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
