TRiangles ABE and ACD are similar because BE and CD are parallel.
Therefore CD / BE = AD / AE
8 / BE = 16 / 10
BE = 8*10 / 16 = 5
Also, 16 / 10 = AC / AB = 20 / AB
AB = 10 * 20 / 16 = 12,5
Perimeter of ABE = 5 + 10 + 12.5
= 27.5 units (answer)
I think the answer would be J?
-5(x+7)<-10
-5x-35<-10
+35. +35
-4x<25
both divided by-4
x> -6.25
i flipped the sign because I divided with a negative number. and I hope you can make -6.25 into a fraction, I can't because I don't have a calculator with me :(
It pretty much looks like a one to one function. Plot the graph then draw a horizontal line,if the line touches the graph at just one point then it is
