Answer:
(0, -4)
Step-by-step explanation:
Given the inequality expression
y>−2x+y≤4
This can be splitted into
y>−2x+y .... 1
and -2x+y≤4 .... 2
From1;
y>−2x+y
y - y >−2x
0 >−2x
-2x < 0
x > 0/-2
x>0
Substitute x = 0 into 2
-2(0)+ y ≤4
y≤4
Hence the solution is (0, -4)
<span>Given cotA + cotB + cotC = sqrt3
to prove triangle ABC is equilateral
we prove this by assuming ABC to be equialteral and establishing the truth
of the statement cotA + cotB + cotC =sqrt3
since ABC is equialteral angleA=angleB=angleC=60 degrees
cotA=cotB=CotC = cot60= 1/sqrt3
therefore cotA + cotB + cotC = 1/sqrt3 + 1/sqrt3 + 1/sqrt3
=3/sqrt3
=sqrt3 which is equal to the RHS ( right hand side) of the expression
hence our assumption that ABC is equilateral is true</span>
