Question

find the value of k if (3,4) is a solution of the equation 5x +2yk =0

Answer 1

Answer:

K =$\frac{-15}{8}$

Step-by-step explanation:

(3,4)

x = 3

y = 4

by putting these values in  5x +2yk =0

5 x 3 + 2  x 4 k = 0

15 + 8 k = 0

8k = 0-15

8k = -15

k = $\frac{-15}{8}$

Answer 2

Answer:

In brackets (3,4) x =3 and y =4 cordinnates therefore

if we apply value in this equation then it would be

5(3) +2(4)k =0

15+ 8k =0

8k =-15

therefore k= -15/8
