Question

If (2,3) is a solution of 2x + 5y + k = 0 then k =

Answer 1

Answer:

k = -19

Step-by-step explanation:

Equation = 2x+5y+5

Roots = (2,3) means x=2 and y=3.

To find = k

Putting values of x and y in the equation.

We get, 2(2) + 5(3) + k = 0

4 + 15 + k = 0

k + 19 = 0

k = -19

Hence, Founded.
