Answer:

And the general formula for a circle is given by this expression:

With the center (h,k) and the radius r. If we compare this general expression with the formula that we obtain in (1) we see that :

So then the best solution for this cae would be:
b. center: (-1,1)
radius =4
Step-by-step explanation:
For this case we have the following equation given:

And we can complete the squares for this case like this:


Now we can rewrite the last expression like this:

Answer: 126 5p coins
Step by step explanation:
1p+2p+5p = 630
2p= 2/5 of 630
2p= 252
1p= 2( 5p)
630 - 252 = 378
378/3= 126= 5p
378-126= 252 = 1p
252+252+126= 630
