QUESTION NO.15

I WILL MARK AS BRAINLIEST IF U SOLVE IT CORRECT

Answer 1

let the ordinate be k
now as per the question it's anaconda is 1*1/2 of. k

therefore 3/2* k
it's points will be (3/2*k , k)

2x+5y=19
put value
2( 3/2 *k) + 5k = 19
3k+ 5k=19
k= 19/8

x abscissa= 3/2 * k
= 3/2 * 19/8
= 3.5

x= 3.5
y=2.3

Answer 2

2X +5Y = 19...........(1)

given, ordinate = 3/2 of abscissa 

that means Y = 3/2 × X......(2)

so substitute it in the first equation 

2X + X(5 × 3/2) =19

2X + 15/2 X = 19

(4X +15X) / 2 =19

19X = 38

X=38/19=>2

X=2

now substitute the X value in second equation 

Y = 3/2 X

Y = 3/2 × 2

Y = 3

(X,Y) = (2,3)
