У - 6x = ||<br> -77<br> - 2x-3y=-7
Maksim231197 [3]

Answer:

<h2>x= 37/16</h2><h3>y=199/8</h3>

Step-by-step explanation:

1....y=11+6x

-77-2x+3y=-7

replace y by ..1..

so   -77-2x+3(11+6x)=-7

-77-2x+33+18x=-7

-44+16x=-7

16x=37

y=11+6x

replace x by 37/16

y=11+6*37/16

y=199/8

motikmotik
The formula for a circle is (x-h)^2 + (y-k)^2 = r^2 where h is x-value and k is the y-value of the center.

If diameter is 24, the radius is 12

(x + 9)^2 + (y - 5)^2 = 144
