PLEASE HELP ME AND I WILL MARK Brainiest and give more points. Four lines are graphed on the coordinate plane as pictured below.

question 1)
the point (-4,4) is the solution for the system containing lines

answer choices-
1) a, b
2) b, c
3) c, d

question 2)
the system contains the lines

answer choices-
1) b, c has no solution.
2) a, d has no solution
3) a, c has no solution

question 3)
the point (-6,1) is the solution to the system containing the lines

answer choices-
1) a, c
2) c, d
3) b, d

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."

The areas of two similar triangles are 72dm2 and 50dm2. the sum of their perimeters is 226dm. what is the perimeter of each of these triangles?

What should be done to both sides of the equation in order to solve -5m = -40? a) multiply by -5. b) divide by -5. c) multiply by -40. d) divide by -40.
