Use the x and y values from your point and the h and k from the center to write the equation you need to solve for r. The general form of the equation for a circle is
. We will fill in accordingly:
. Solve for r to get that
The first dove terms are:3,9,12,15,18
That's simple!!!
-12/19 = b/19
as denominators are same, you can cancel that.
b = -12
there could be a calculator online to solve it
143
because the equation would be 11x+x=156. so if you add like terms it would be 12x=156. then 156/12 is 13. 13 is how many miles Early biked.
so dory biked 11 times as many miles, so you would solve 13(Early's miles) times 11(Dory's miles). 13x11=143
so dory biked 143 miles last month
