Let 

Then this equation can be expressed in the form (x + a)(y + b) = c for some constants a, b, and c. Enter your answer in the form "a, b, c ".

y  =  (x - 3) / (x + 7)

Multiply by (x + 7):     y(x + 7)  =  x - 3

Simplify:                      xy - 7y  =  x - 3

                               xy - 7y - x  =  -3

                               y(x - 7) - x  =  -3

                         y(x - 7) - x + 7  =  4

                        y(x - 7) - (x - 7)  =  4

                             (y - 1)(x - 7)  =  4

I tried the answer -7, -1, 4. But it was incorrect.

I see what you did wrong when you expanded  y(x + 7)  =  x - 3 and got xy - 7y  =  x - 3, the -7 should have been a +7.

Therefore the equation should be (x+7)(y-1)=-10.

Thank you for leading me to the right solution.

Spongebob, 

It is really rude of you to give yourself 6 points and geno no points at all.  You gave him no thanks either.

 

Do you think this rude behaviour helps you in some way?  Do you think no one will notice?

I never tried to be rude to Geno. I never said that I would take all the credit. You could have said that I forgot to thank Geno.

The reason Melody didn’t say “you forgot” to give Geno points is because you didn’t forget. You always remember to give yourself points.  You remember it so well that your score is more than twice what is should be.  Many of your posts have 14, 12, and 10 or more points.  You can’t give Geno any points because you use your point allocation for your own posts.   

 

What are you trying to prove? That you are self-absorbed to the point of contempt for everyone else.  If so, you are doing a good job!

Your post was quite funny.  Many deities and some royals have apologists.  I qualify for one too. smiley

I already said thank you, and I gave Geno a point.

Wow! That’s wonderful! I hope you didn’t break your finger. You now qualify for entry into paradise.

I can hear the deity now: “Welcome my good and faithful servant, you have pleased me well! In My Holy Presence you will forever dwell...”

All ideologies have failings. All deities have failings too. That’s why we need apologists.
