Decide whether the triangles are similar. If so, determine the appropriate expression to solve for x. A: The triangles are not similar; no expression for x can be found B: ΔABC ~ ΔDEF; x = r * w/u C: ΔABC ~ ΔEFD; x = r * w/u D: ΔABC ~ ΔEFD; x = r * w/z

I believe that those two triangles are not similar, there's no expression for x -- option 1

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

w'x is 0.

hope it
