Question
Which one of the following gases is supporter of
combustion?Solution
Oxygen is supporter of combustion. Though it is not combustible. Combustion is an oxidation process and this cannot occur without the presence of oxygen.Â
Equation 1: x² - 144x + 5184 = 0
Equation 2: y² - 130y + 4225 = 0
if x satisfies 3x² – 5x – 12 = 0, find the sum of reciprocals of roots.
I. 7x² + 52x + 21 = 0
II. 6y² + 7y - 24 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 21x² - 82x + 80 = 0
Equation 2: 23y² - 132y + 85 = 0
I. 5x + 2y = 31
II. 3x + 7y = 36
I. x2 – 13x + 36 = 0
II. 3y2 – 29y + 18 = 0
I. 40 x² - 93 x + 54 = 0
II. 30 y² - 61 y + 30 = 0
I. x2Â - 9x - 52 = 0
II. y2Â - 16y + 63 = 0
I. 117x² + 250x + 117 = 0
II. 54y² -123y + 65 = 0
Equation 1: x² + 16x + 63 = 0
Equation 2: y² + 10y + 21 = 0
