Given: -1/2 x > 6. choose the solution set. {x | x r, x > -12} {x | x r, x < -12} {x | x r, x > -3} {x | x r, x < -3}

{x|x ∈ R, x < - 12 }

Step-by-step explanation:

given - x > 6

multiply both sides by - 2

Remembering to reverse the inequality symbol as a consequence of multiplying by a negative value

x < - 12 ← reverse symbol

{ x | x ∈ R, x < - 12 } ← solution set

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
