Find the value of k so that the graph of the following system of equations has no solution. 3x-2y-12=0 ; kx+6y-10=0

k = -9

Step-by-step explanation:

The equations are of the form

ax+by+c=0

Two equations have no solution when

3x-2y-12=0 ; kx+6y-10=0

So,

Hence, k = -9

take the top number and divide it by a the bottom number

step-by-step explanation:

1/2 1 divied by 2 = .5

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
