Question

PLEASE HELP WITH BOTH I WOULD APPRECIATE IT SO SO SO MUCH❤️

Answer 1

Answer:

The answer to question 14 is (6, 5), and the answer to question 15 is D) x = -2 and y = 1.

Step-by-step 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 $y = \frac{1}{2} x+2$ and $y=x-1$. 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 $3x+4y=-2$ and $2x-4y=-8$ 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. $3(-2)+4(1)=-2$ ⇒ $-6+4=-2$ ⇒ $-2 = -2$, which is true, so choice D works for the first equation. $2(-2)-4(1)=-8$ ⇒ $-4-4=-8$ ⇒ $-8=-8$, 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.
