X²+y²-6x+14y-1=0
and please show your work so I can learn

Hello there,

I hope you and your family are staying safe and healthy during this winter season.

We need to use the Quadratic Formula*

,

Thus, given the problem:

So now we just need to plug them in the Quadratic Formula*

,

As you can see, it is a mess right now. Therefore, we need to simplify it

,

Now that's get us to the final solution:

,

It is my pleasure to help students like you! If you have additional questions, please let me know.

Take care!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
