Answer:
D
Step-by-step explanation:
∠ 6 is formed by the 2 lines that intersect at D
then the vertex of ∠ 6 is D
For a system of two variables and two equations, each equation will be a linear graph, and where the lines intersect is the solution as an ordered pair (x,y). If the lines don’t intersect (they’re parallel) so there is no unique solution.
Answer: 4 hours 31 min
