Question
circle c is graphed in the xy-plane and has a center at the point (7, 9). the circle is translated 3 units left and
4 units up to form the image circle a. which of the following are the (x, y) coordinates of the center of circle
a?
a(4, 13)
b(10, 13)
c (4,5)
d (10, 5)

y = x + 95

y = 42 + 95

y=137 mm hg

b.-4 units

all you   do is count how many times you move

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
