False. because.....
the equation of a circle is (x-h)^2 + (y-k)^2 = r^2 and the center is (h,k)
if the center of a circle is (-5, -13) substitute the values into the equation
so....(x- -5)^2 + (y- -13)^2 = r^2 which is (x+5)^2 + (y+13)^2 = r^2
in this case, because you are only asking about the center of the circle from the equation the 81 or radius of the circle doesn't matter.
Answer:
false
Step-by-step explanation:
Let w represent the number of weeks passed.
The amount of money Ed saved is 6w - 1 (I'm subtracting the one dollar that he owes to someone)
His sister saved 6w + 2.66 (I'm adding the money she already saved).
What value of w makes both expressions equal?
We need to solve the equation 6w - 1 = 6w + 2.66
Let's solve it.
If we subtract 6w from both sides, we get -1 = 2.66
So, there is no solution. They will never have saved the same amount.
This makes sense because they started out with different amounts of money saved, but they are saving at the same rate.
