Find the value of k so that the point a (5, 6) belongs to the graph of the following equation:
2y+kx=5.

k= -1.4

Step-by-step explanation:

To find : The value of k so that the point A (5, 6) belongs to the graph of the equation 2y+kx=5.

For that , we substitute (x,y) = (5,6)  i.e. x= 5 and y=6 , we get

Subtract 12 from both the sides ,we get

 (Divide both sides by 5)

Hence, the required value of k= -1.4

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
