(x²+4x+4)-4+(y²-6y+9)-9=-4
(x+2)²+(y-3)²=9
(x+2)²+(y-3)²=3²<span>
Circles follow the form: (x-a)+(y-b)=r</span><span>²
</span><span>Therefore the center of the circle is at (-2,3)
and the radius is 3.</span>
Answer:
y = 245/2
Step-by-step explanation:
y = k x^2
Where k is the constant of variation
Let y= 40 and x=4
40 = k *(4)^2
40 = k*16
40/16 = k
5/2 = k
y =5/2 x^2
Let x=7
y = 5/2 (7)^2
y = 5/2(49)
y = 245/2
<span>8*11 + 6y = 28
88 + 6y = 28
6y = 28 - 88
6y = -60
y = -60/6
y = -10</span>
