Answer:
The answer to question 14 is (6, 5), and the answer to question 15 is D) x = -2 and y = 1.
Explanation:
Question 14 explanation: Because each line on the graph represents a different function, that means that the point where they intersect is the answer, as the point both appear on the equations
and
. Since the two equations' point of intersection is (6, 5), that means the solution to the system of equations is the point (6, 5).
Question 15 explanation: The solution to the system of equations
and
would be the x and y values that satisfy both equations. If you select the pair on selection D, you'll find that it's valid.
⇒
⇒
, which is true, so choice D works for the first equation.
⇒
⇒
, which is also true. This means that x = -2 and y = 1 is the solution to the system of equations, making choice D the correct answer.
