Step-by-step explanation:
I'm not totally for sure about it though. sorry :(
Equation of a circle is given by (x - a)^2 + (y - b)^2 = r^2; where (a, b) is the center of the circle.
By comparison, (x - 2)^2 + (y + 5)^2 = 16 has center at point (2, -5).
Translating the circle 4 units to the left and 1 unit up gives a new center at point (2 - 4, -5 + 1) = (-2, -4)
Using the quadratic formula, plug a=2, b=3, and c=4 into the formula because the equation given can not be factored.
x= -3(+/-) radical (3^2-4*2*2)/2(2)
therefore, x= (-3+ radical 7 i) / 4
x= (-3- radical 7 i )/ 4.
the answer choice is 1.

Answer:
Step-by-step explanation:
3). Definition of midpoint
4). Midpoint theorem ( ≅ parts are = )
7). Division Property of Equality.
8). QR = 5 + <em>2</em> = 7 Substitution x by equal value
9). PQ = 4(<em>2</em>) - 1 = 7 Substitution x by equal value
10). Segment addition postulate
11). Substitution
