The centre is displaced 3 units to the right and 4 units up, so the left side is (x-3)^2 + (y-4)^2
The radius of the circle equals the distance between the centre and the origin. By the pythogorean theorem, R^2 = 3^2 + 4^2 = 25.
So, the equation of the circle is (x-3)^2 + (y-4)^2 = 25.
This means that there is a flaw in the question as none of the options are correct.
Answer:
A. 45 + b = 88, so b = $43
Step-by-step explanation:
We know that he's earned $45 dollars, plus b dollars for babysitting. This gives us the first part of the equation (45 + b). The total amount he earned was $88, so 45 + b = 88.
Then, you can solve it.
45 + b = 88
-45 -45
0 + b = 43
b = 43
This means he earned $43 babysitting his younger brother.
Hope this helps :)
