(0, 2) and approximately (1.91, 0.09)
no solution

Answer 1

(0, 2) and approximately (1.91, 0.09)

Explanation:

Answer 2

It can be helpful to graph the system. The appropriate choice is ...

... (0, 2) and approximately (1.91, 0.09)

Such a system of equations has no algebraic solution. Some graphing calculators will identify the points of intersection of the graphs to full calculator precision. Others can help you iterate a solution, if you need better accuracy.
