Answer: Center (-2,3), radius 2
Step-by-step explanation: Subtract 9 from both sides, then complete the square for the x and y variables & add to both sides:
. The center of this circle in the form
is (a,b) with radius r. a=-2, b=3, r=
=2
Answer:
D. y =
Step-by-step explanation:
The solutions to this graph (meaning when y equals 0 or when the graph crosses the x-axis) are 4 and 5.
The only answer choice that has the solutions 4 and 5 when you factor it out is D.
Here's the proof:
Factors of 20: - 5 & -4
Sums that add up to -9: -5 + (-4)
(factor the first two terms and the last two terms separately)
(x - 5) (x - 4)
