F(x) + g(x) = (-2x + 8)+ 3x
f(x) + g(x) = -2x + 8 + 3x Combine like terms.
f(x) + g(x) = x + 8
f(x) + g(x) = (f+g)(x) = x + 8
(f + g)(-1) = -1 + 8
(f + g)(-1) = 7 <<<<<<<< Answer

Find an equation of the circle that has center (6, 2) and passes through (-2,-6).

Irina18 [472]

Answer:

(x - 6)² + (y - 2)² = 128

Step-by-step explanation:

Given as the circle has center ( 6 , 2)

and it passes through points (-2 , -6)

Now , standard equation of circle is (x -a)² + (y- b)² = r² , where (a , b) is center and r is the radius .

Again from given center the circle equation is

(x- 6)² + (y- 2)² = r²

Now this circle passes through points (-2 , -6)

so, (-2 -6)² + (-6 -2)² = r²

so, 8² + 8² = r²

Or, 128 = r²

i.e Radius pf this circle = 8 $\sqrt{2}$

Hence the circle equation formed is

(x- 6)² +( y-2)² = 128 Answer
