Question

Select the point that is a solution to the system of inequalities. yx^2-4

A. (1,2)


B. (-2,-4)


C. (4,0)


D. (0,4)

Answer 1

A. (1,2)

Explanation:

Answer 2

A. (1,2)

Explanation:

A solution to the system of inequalities lies beyond the boundary line where the inequality is satisfied.

Hence let us assume that (yx)^2 - 4 = 0

We tried all the ordered pairs but the right answer was given by A. (1,2)

putting x = 1 and y = 2 in the expression:

(1*2)^2 - 4 = 0

0 = 0 which is true.
