Answer:
I. (x - 6)² + (y + 7)² = 121
Step-by-step explanation:
Given a circle with coordinates of the center as (6, -7), and with a diameter of 22, equation of the circle is given below using the standard equation formula of a circle:
Formula => (x - a)² + (y - b)² = r²
Where,
a = 6
b = -7
r = radius of circle = ½ of diameter = ½ of 22 = 11
Thus, plug in the above values into the standard equation formula:
(x - 6)² + (y - (-7))² = 11²
(x - 6)² + (y + 7)² = 121
<em>Our answer, which is the equation of the circle is I. (x - 6)² + (y + 7)² = 121</em>
<em></em>
T = 126.
13 = t/9 - 1 multiply both sides by 9
117 = t - 9 move terms
-t = -9 - 117
-t = -126 change the signs
t = 126
-19 to -15 would be a positive 4 difference
19 to 15 = 4 this would be a -4 difference
3 to 7 is a positive 4 difference
-3 to 7 is a difference of 10
so there is 1 with a -4 difference
answer is B.

</span><span>3/8y- 5/8 y = 5/12- 1/12
-2/8y = 4/12
-1/4y = 1/3
y = 1/3 *(-4)
y = - 4/3</span>
