8+x=L L+x=26 substitute (8+x)+x=26 x is the same for both expressions because the points are equally spaced solve for x, then solve for L
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
the points are evenly spaced, so L is the same distance away from both points B and E
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
So L is the midpoint of BE

do you see this?
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
so we can say (B+E)/2 = L or basically take the value of B, add it to E, then divide by 2 to get L

what is the distance from point T to point E
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
good, now what's 2/3 of 15?
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
so the distance from point T to point P is 10 units (since P is 2/3 of the way from T to E)
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
So just add 10 to the value of T to get your answer

do E, D and C all lie on the same line?
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
so they are collinear by the very definition of collinear
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
points are collinear if they all lie on the same straight line

 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
Notice how there is no way to draw a straight line through all of the points, so those points are noncollinear
