Answer 1

Answer:

( i ) 3 , ( ii ) - 6 ( waise to aapke option mai no nhi hai but fir bhi ans is - 6 ) ( iv ) 15 %

Step-by-step explanation:

4x + 5y = 19

4 (1 ) + 5y = 19

4 + 5y = 19

5y = 19 -4

5y = 15

y = 15 /5

y = 3

(ii) 2x - 5x + 2 = 0

b^2 - 4ac

= a= 2 b = - 5 and c= 2

( 5 )2 - 4 × 2 × 2

10 - 16

= - 6

baaki nhi pta sorry but plz mark as brainliest
