7. The diagram below shows two congruent circles which touch at a single point T.
The circle, centre A, has as its equation x² + y2 - 6x -18y +45 = 0.
The line with equation 2y = x is the common tangent to the two circles through T.
x2 + y2 - 6x-18y+45 = 0

(a)
Show algebraically that T has coordinates (6,3).
(b)
Hence establish the the coordinates of B, the centre of the lower circle, and
find the equation of this circle.​

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

answer: what in the world is this
