The second graph is correct. Because the first equation is <= -x-1, it must fall under that line: only the second and fourth graphs do so. The second equation, >=2x+4, means it must fall above that line: only the second and third graphs do so.

Identify all of the root(s) of g(x) = (x2 + 3x - 4)(x2 - 4x + 29)

vichka [17]

Answer:

x=-4,1,2+5i,2-5i

Step-by-step explanation:

Given is an algebraic expression g(x) as product of two functions.

Hence solutions will be the combined solutions of two quadratic products

$g(x) = (x^2 + 3x - 4)(x^2 - 4x + 29)\\$

I expression can be factorised as

$(x+4)(x-1)$

Hence one set of solutions are

x=-4,1

Next quadratic we cannot factorize

and hence use formulae

$x=\frac{4+/-\sqrt{16-116} }{2} =2+5i, 2-5i$

Which of the following circles have their centers in the second quadrant A.(x+3)^2+(y-2)^2=8

Y_Kistochka [10]

The circles that have their centers in the second quadrant are; Options B and D

<h3>How to identify circle equations?</h3>

The general form of equation of a circle is;

( x - h )² + ( y - k )² = r²

where (h, k) is the center and r is the radius.

Thus;

A. (x - 5)² + (y - 6)² = 25

(h, k) = 5,6 This is Quadrant 1

B. (x + 1)² + (y - 7)² = 16

(h, k) = -1,7 This is Quadrant 2

C. (x - 4)² + (y + 3)²= 32

(h, k) = 4,-3 This is Quadrant 4

D. (x + 2)² + (y - 5)² = 9

(h, k) = -2,5

This is Quadrant 2

The missing circle equations are;

A. (x - 5)² + (y - 6)² = 25

B. (x + 1)² + (y - 7)² = 16

C. (x - 4)² + (y + 3)² = 32

D. (x + 2)² + (y - 5)² = 9
