ice with the voters." Select the most appropriate meaning of the bold idiom in the following sentence.Solution
The idiom "walking on thin ice" means to be in a precarious situation where one is at risk of getting into trouble or making a mistake, especially when dealing with sensitive matters.
I. 5x + y = 37
II. 4y+ x = 15
I. x³= ((4)5+ (15)³)/(3)4
II. 8y³=(-13)3÷ √1521+ (3y)³Â
(i) 2x² + 14x - 16 = 0
(ii) y² – y – 12 = 0
- If the quadratic equation x² + 18x + n = 0 has real and equal roots, what is the value of n?
I. 2x2 - 15x + 25 = 0
II. 3y2 - 10y + 8 = 0
I. 10x² - 11x + 3 = 0
II. 42y² - 23y – 10 = 0
I. 6x² - 23x + 7 = 0
II. 6y² - 29y + 9 = 0
I. 6x2 - 47x + 77 =0
II. 6y2 - 35y + 49 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 21x + 110 = 0
Equation 2: y² - 23y + 132 = 0
(i) 2x² – 9x + 10 = 0
(ii) 4y² – 12y + 9 = 0
