Best ResponseYou've already chosen the best response.01. is similar to . given 2. property of similar triangles 3. = property of proportion 4. slope of = slope of = definition of slope 5. slope of × slope of = multiplying the slopes 6. (This statement is intentionally left blank.) Substitution Property of Equality 7. slope of × slope of = 1 simplifying the right side

Best ResponseYou've already chosen the best response.01. AC←→⊥CD←→ (view diagram) ΔABC is similar to ΔCED. given 2. (This statement is intentionally left blank.) property of similar triangles 3. ABBC = ECDE property of proportion 4. slope of AC←→ = ABBC slope of DC←→ = DEAC definition of slope 5. slope of AC←→ × slope of DC←→ = ABBC×DEEC multiplying the slopes 6. Substitution Property of Equality 7. slope of AC←→ × slope of DC←→ = 1 simplifying the right side

Best ResponseYou've already chosen the best response.2well step 3 has AB*BC = EC*DE, or so it seems the step before that would be some proportion and cross multiplying would lead to step 3

Best ResponseYou've already chosen the best response.2let's say you had a/b = c/d

Best ResponseYou've already chosen the best response.2if you cross multiplied, you'd get a*d = b*c agreed?

jim_thompson5910

Best ResponseYou've already chosen the best response.2so what proportion could be set up to lead to AB*BC = EC*DE ?

Best ResponseYou've already chosen the best response.0they seem to look like this but in fraction AB/BC;. something like that.

jim_thompson5910

Best ResponseYou've already chosen the best response.2more like AB/EC = DE/BC. There are other possibilities dw:1436929680423:dw

Best ResponseYou've already chosen the best response.0the closest choice has a fraction DE/EC. would that work?

jim_thompson5910

Best ResponseYou've already chosen the best response.2well as long as they cross multiply to AB*BC = EC*DE, then it will work

jim_thompson5910

Best ResponseYou've already chosen the best response.2there are more possibilities than what I drew up there (maybe 4 possibilities?)

Best ResponseYou've already chosen the best response.2in line 3, where it says `3. ABBC = ECDE property of proportion` there are no fractions here either?

Best ResponseYou've already chosen the best response.0its really hard to paste those kinds of things on here.

Best ResponseYou've already chosen the best response.2so line 3 actually says this right? AB/BC = EC/DE

Best ResponseYou've already chosen the best response.2you can multiply both sides by BC and divide both sides by EC that will make BC and EC swap dw:1436930925056:dw

Best ResponseYou've already chosen the best response.0AB and BC form a right angle at point B. If A = (3, 1) and B = (4, 4), what is the equation of BC

jim_thompson5910

Best ResponseYou've already chosen the best response.2first find the equation of the line through A and B

jim_thompson5910

Best ResponseYou've already chosen the best response.2use that slope to find the equation of the line through those two points
