 If 4x = 40, 3y = 33, what is the value of 6x + 4y?
I. 20y² - 13y + 2 = 0
II. 6x² - 25x + 14 = 0
Solve the given two equations and answer the two questions that follow as per the instructions given below.
I. (1/4) + 7.5p(-2) = 3.62...
The quadratic equation (p + 1)x 2 - 8(p + 1)x + 8(p + 16) = 0 (where p ≠-1) has equal roots. find the value of p.
I. 2y² - 3y – 14 = 0
II. 3x² - 7x + 4 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 19x² - 92x + 73 = 0
Equation 2: 17y² - 76y + 59 = 0
I. 6 y² + 11 y – 7= 0
