Logic: In this series, the letters progress by: +2 For numbers 52 - 1 = 24, 62 - 1 = 35 and so on therefore the next series will be V63 .
If x^2 - 7x + k = 0 has roots that are equal, what is the value of k?
I. 4x² - 21x + 20 = 0
II. 8y² - 22y + 15 = 0
I. 5x2 – 7x – 6 =0
II. 2y2 – 5y – 7 =0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 24x + 143 = 0
Equation 2: y² - 20y + 96 = 0
I. x + 1 = 3√ 9261
II. y + 1 = √ 324
I. √(74x-250 )– x=15
II. √(3y²-37y+18)+ 2y=18
I. 7x + 8y = 36
II. 3x + 4y = 14
I. 3x2 – 17x + 10 = 0
II. y2 – 17y + 52 = 0
I. 2x² - 11x + 12 = 0
II. 12y² + 29y + 15 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 4x² - 12x + 9 = 0
Equation 2: 2y² + 8y + 6 = 0
