Answer:
x2-x1/y2-y1=2-4/10--2=2-4/10+2=-2/12
=-6
I believe it is B, darling. ^^
I believe the correct answer would be C!
Given:
The two sides of a triangle are 2 and 6.
To find:
The side length that would NOT work to make a triangle with the two slide lengths of 2 and 6.
Solution:
For a triangle, the sum of two smaller sides must be greater than the largest side.
Let x be the third side.
Case 1: x is the largest side, then
...(i)
Case 2: x is not the largest side, then
...(ii)
From (i) and (ii), we get
Here, 4 and 8 are not included.
6, 5, 7 are included in the above interval, but 4 is not included in the above interval. It means 4 would NOT work to make a triangle with the two slide lengths of 2 and 6.
Therefore, the correct option is D.
Answer:
x=3, y=1. (3, 1).
Step-by-step explanation:
x+3y=6
2x-7y=-1
------------
x=6-3y
2(6-3y)-7y=-1
12-6y-7y=-1
12-13y=-1
13y=12-(-1)
13y=12+1
13y=13
y=13/13
y=1
x+3(1)=6
x+3=6
x=6-3
x=3
