(x+8)^(2) + (y+9)^(2) = 169
(x+8)^(2) + (y+9)^(2) = 13^2
h = -8
k = -9
r = 13
answer
A. center (-8,-9)
radius = 13
--------------
(x-7)^2 + y^2 = 225
(x-7)^2 + y^2 = 15^2
h = 7
k = 0
r = 15
answer
B. center (7,0)
radius = 15
Answer:
1) If the coefficent of any variable is zero then the answer of the variable is 0.
2) There are two answers in a system of equations.
Answer:
Step-by-step explanation:2x + 9x - 9 = 16x + 16 - 5
= 11x - 9 = 16x + 11
11x - 16x = 11 + 9
5x = 20
x = 20/5
x = 4

<h3>Answer: </h3>
about 1.768 seconds
<h3>Explanation:</h3>
Since the phone is <em>dropped</em>, the first equation applies. The final height is assumed to be zero, so we have ...
... h(t) = 0 = -16t² +50
... 16t² = 50 . . . . . . . . add 16t²
... t² = 50/16 . . . . . . . . divide by 16
... t = √3.125 . . . . . . . take the square root
... t ≈ 1.768 . . . . . . . . round to milliseconds
