Answer:
Step-by-step explanation:
Refer the attached figure .
We are given a line AB
Point A
Point B
Formula for slope 'm' when two points are given :
Substituting thew values
Since we are given that AB is perpendicular to BC
So, By property - perpendicular slopes are negative reciprocals of each other.
So, Slope for line BC : 
Point B = (4,4)
Formula of equation of line : 
Hence the equation of line BC :
Answer:
-25/9
Step-by-step explanation:
-5/6 : 3/10
-->(cross multibly)
=-5 *10 : 6*3
=-50/ 18
=-25/9
Easy dude.
This simplifies to 4+b

Answer: 10
Step-by-step explanation:
tony is 5 years younger than Marvin's age 1 year from now.
t = (m+1) - 5
t = m - 4
6 years ago tony was half as old as marvin was then.
t - 6 = 1/2(m - 6)
Get rid of the fraction, multiply both sides by 2
2(t-6) = m - 6
2t - 12 = m - 6
2t = m - 6 + 12
2t = m + 6
from the first statement, replace t with (m-4)
2(m-4) = m + 6
2m - 8 = m + 6
2m - m = 6 + 8
m = 14 is Marvin's present age
:
how old is tony now?
t = 14 - 4
t = 10 yrs is tony's age
