Показать описание
On comparing the ratios a 1 u 2 , b_{1}/b_{2} * and * c_{1}/c_{2} find out whether the lines representing the following pairs of linear equations intersect at a point, are parallel or coincident:
(i) 5x - 4y + 8 = 0 7x + 6y - 9 = 0
(ii) 9x + 3y + 12 = 0 18x + 6y + 24 = 0
3. On comparing the ratios a_{1}/a_{2} b_{1}/b_{2} c_{1}/c_{2} and find out whether the following equations are consistent, or inconsistent. outhe 5x - 3y = 11 of linear
(iii) 6x - 3y + 10 = 0 2x - y + 9 = 0
(i) 3x + 2y = 5 ; 2x - 3y = 7
(iii) 3/2 * x + 5/3 * y = 7; 9x - 10y = 14
(v) 4/3 * x + 2y = 8; 2x + 3y = 12
2x - 3y = 8 4x - 6y = 9
CEP - 10x + 6y = - 22
(i) 5x - 4y + 8 = 0 7x + 6y - 9 = 0
(ii) 9x + 3y + 12 = 0 18x + 6y + 24 = 0
