Y=Mx+B
(4,-8), (-4,2)
X1 y1 x2 y2
2-(-8)/-4-4= 10/-8 dived by 2
=5/-4 or -5/4
M=-5/4
(M is slope)
Answer:
X=-10
Step-by-step explanation:
Flip it
7X=-70
Divide both sides by 7
7x/7= -70/7
If the original height was 6 inches and it was reduced to half that or in other words 3 inches, do 8 inches divided by 2 to get a new width of 4 inches.
Hope this helps!
Answer:
0.28
Step-by-step explanation:
DB is a median (given). It goes from vertex point D to midpoint B.
The point B is the midpoint of segment AC. So B cuts AC into two equal halves: AB and AC
Meaning AB = AC
AC = AB+BC ... segment addition postulate
AC = AB+AB ... substitution; replace BC with AB (valid because AB = AC)
AC = 2*AB
2*AB = AC
2*AB = 50 ... substitution; replace AC with 50
2*AB/2 = 50/2 ... divide both sides by 2
AB = 25 which is the answer
