Answer:
11
Step-by-step explanation:
first, distribute the negative four in Expression 1: -36x+8+3
next, set that equal to Expression 2: -36x+11 = -36x+k
finally, add 36x to both sides: 11 = k
Center of given circle is (h,k)= (5,-3)
Option A is correct.
Step-by-step explanation:
We need to find the coordinates of the center of the given circle: 
The standard equation of circle is:

Where (h,k) is the center of circle and r is the radius of circle.
Now comparing the given equation with standard equation to find h and k

Making it equivalent to standard equation:

By comparing, the value of h is 5 and k is -3
Hence center of given circle is (h,k)= (5,-3)
Option A is correct.

Answer:
yes
Step-by-step explanation:
6 is half of 12. 15 is half of 30. The ratios are equal, so the fractions are proportional.
Answer: yes
Also, you can reduce both fractions.
Divide the numerator and denominator of 6/12 by 6 to get 1/2.
Divide the numerator and denominator of 15/30 by 15 to get 1/2.
Since both fractions reduce to 1/2, 6/12 and 15/30 are equivalent fractions and are proportional.
