Answer:
center=(-7,5)
Step-by-step explanation:
The center form of the circle equation is in the format (x – h)^2 + (y – k)^2 = r^2, with the center being at the point (h, k).
you can find center by making equal to zero each term, then:
x+7 = 0
x=-7
y-5 = 0
y=5
then the center is (-7,5).

Turn both mixed fractions into improper fractions
2 3/5 = 13/5
1 4/7 = 11/7
now multiply the improper fractions
13/5 x 11/7
143/35 or 4 3/35
Answer: B
Step-by-step explanation:
Answer:
The Answer is: The first number is 5 and the second one is 8.
Step-by-step explanation:
Let f = first number and s = second number
Twice the first number added to the second number is 18:
2f + s = 18
The second number is equal to 4 times the first number minus 12:
s = 4f - 12
Substitute:
2f + (4f - 12) = 18
6f - 12 = 18
6f = 18 + 12
6f = 30
f = 5, is the first number.
Solve for the 2nd number:
s = 4(5) - 12 = 20 - 12 = 8, is the second number.
Proof:
2f + s = 18
2(5) + 8 = 18
18 = 18
Hope this helps! Have an Awesome Day! :-)
