An example of a linear equation with three variables, x, y, and z, is given by: ax + by + cz + d = 0, where a, b, c, and d are constants and a, b, and c are non-zero. Linear equations occur frequently in most subareas of mathematics and especially in applied mathematics.
One study has shown that tea tree oil is more active against the organisms associated with transient carriage than against commensal skin flora and thus may be useful in eliminating the transient flora while suppressing but maintaining commensal flora. 21 The rapid kill rate of Clone 88 compared with standard tea tree oil shown for most of the organisms tested in the present study is encouraging and suggests that further clinical studies should be carried out.
Tea tree. If youâve ever experienced the powerful and antiseptic scent of tea tree oil, then you probably wonât find it hard to believe that tea tree oil contains some serious antibacterial, antifungal and anti-inflammatory properties. I regularly use tea tree oil to thwart any acne flare-ups before they get nasty. Usually I take a cotton swab, dip it into a jar of tea tree essential oil and dab it on my breakout. Donât do this if you have extremely sensitive skin.
