The graphs of the equations y=3x+13 and y-kx=15 are parallel when k

The value of k for both lines are parallel is 3

Step-by-step explanation:

Given The equation of two lines as :

y = 3 x + 13

y - k x = 15

I.e y = k x + 15

The standard equation of line is y = m x + c

Where m is the slope of line

Now, according to question , both the lines are parallel , so both have same slope.

I.e   =  

Now slope   from first line is 3

And slope   from second line is k

∵   =  

∴   3 = k

Hence The value of k for both lines are parallel is 3    Answer

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
