Ray BD bisects ∠ABC so that m∠ABD = 5y – 3 and m∠CBD = 2y +12. Find the value of y.

Question

The midpoint of Line Segment AB is (2, -9). The coordinates of one endpoint are A (4, 10). Find the coordinates of endpoint B.

Find the distance between points F (7, 21) and G (-5, 18) to the nearest tenth.

Answer 1

"bisect" means to cut into equal parts.

Thus: 5y – 3 = 2y +12

etc

#2 , let the endpoint be (x,y)
for the x:
(4+x)/2 = 2
4+x = 4
x = 0
for the y:
---- your turn

#3, just use your "distance between 2 points" formula

Answer 2

not helpful need answer

Answer 3

5y-3-2y=12
3y-3=12
3y-3+3=12+3
3y=15
y=5
