Answer:
The coordinates of B is (-5, 4).
Answer:
-11
Step-by-step explanation:
let (2,1)be x1 and y1 respectively
(3,-10) be x2 and y2 respectively
From,slope= (y2-y1)/(x2-x1)
=(-10-1)/(3-2)
= -11/1
= -11
Answer:
1= -6b=a
Step-by-step explanation:
a-3b=33b+6=2a
+3b +3b
a=36b+6=2a
-6 -6
a -6=36b=2a
---------------
-6 -6
a= -6b=2a
This is the work and the answer
The ratio of left handed to right handed people is 1:4
Therefore the ratio of left handed to total people is 1:5
Set up a proportion
1/5= x/30
5*6=30
1*6=6
x=6
Final answer: 6 left handed people
