Answer:
top down: ∞, 0, 1, 0, ∞
Step-by-step explanation:
The equation will have infinite solutions when the left side and right side simplify to the same expression. This is the case for the first and last expressions listed.
2(x -5) = 2(x -5) . . . . expressions are already identical
x +2(x -5) = 3(x -2) -4 ⇒ 3x -10 = 3x -10 . . . the same simplified expression
__
The equation will have no solutions when the x-coefficients are the same, but there are different added constants.
5(x +4) = 5(x -6) ⇒ x +4 = x -6 . . . not true for any x
4(x -2) = 4(x +2) ⇒ x -2 = x +2 . . . not true for any x
__
The equation will have one solution when coefficients of x are different.
5(x +4) = 3(x -6) ⇒ 2x = -38 ⇒ x = -19
If line BC is congruent to line BD then angles C and D are also congruent
so you would set up the problem to find <em>x </em>as:
5x-19=2x+14
+19 +19
____________
5x=2x+33
-2 -2
_____________
3/3x=33/3
____________
x=11
Just pug in x to the equations to solve the rest
If anything there might be an eraser icon (modification notes) so you might want to click on that and read it. If not, post what it says or give the math teacher a call. I hope this helps!
