solve the equation by graphing. Determine whether the equation has one solution, no solution, or infi nitely many solutions.

Question

−x − 5 = −1/-3 (3x + 5)

Answer 1

-x-5 = -1/-3(3x+5) is ambiguous

does it mean

-x-5= (-1/-3)(3x+5) or -x-5=-1/-3(3x+5) ??

if the former then one unique solution, x=-10/3

if the latter then 2 solutions, Not 1, not none, not an infinite number of solutions

which suggests you intended the 1st version

graph the Left side, graph the right side, see where they intersect

y=-x-5 and y= which ever version you intended

1st version gives 2 straight lines. 2nd gives a straight line and a curve with 2 intersection points

which are x= -10/3 +/-(2/3)sqr6
