Answer:

Option A Center (5,-4) radius 7

Step-by-step explanation:

x^2 +y^2 - 10x +8y - 8= 0

Center(-g,-f)

2gx = - 10x

g = - 5

2fy = 8y

f = 4

Center (5,-4)

Radius = square root of (g^2+f^2 - c)

r = square root of (5^2 + - 4^2 - (-8))

r = square root of (25+16+8)

r = square root of 49

r = 7

Question 11 of 25

Olegator [25]

$\\ \sf\longmapsto x+4=\sqrt{8-x}$

$\\ \sf\longmapsto (x+4)^2=8-x$

$\\ \sf\longmapsto x^2+16+8x=8-x$

$\\ \sf\longmapsto x^2+8x-x+16-8=0$

$\\ \sf\longmapsto x^2+7x+8=0$

$\\ \sf\longmapsto x^2-8x+x+8$

$\\ \sf\longmapsto (x-8)(x-1)=0$

$\\ \sf\longmapsto x=8,-1$

If a(x)=2x+3 and b(x)=x2+4x, what is (a∘b)(x)?

Ierofanga [76]

For this problem you need to multiply a and b.
set them up like this
(2x+3)(x^2+4x) and then FOIL
Your final answer should be : 2x^3+11x^2+12x
