Find the extraneous solution of the equation |4x−42|=−10x.

x=3 is the extraneous solution

Step-by-step explanation:

|4x-42| = -10x

Since it's absolute value and we know that there are two possibilities, we need two equations to set up to solve for x.

1st equation:

2nd equation:

Solve both equations for x:

Plug in both values for x in the original equation to find the extraneous solution:

x=-7

x=3

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
