2. Tell whether the ordered pair (-1,-2) is the solution of the system. x + y =

liubo4ka [24]

Answer:

Not the solution tp the system because the ordered pair should be true for both equations. However the last equation is not true.

Step-by-step explanation:

(-1,-2) is the solution of the system. x + y =-3 and 2x - y = -4*

<em />

<em>x + y =-3 :</em>

(-1)+ (-2) = -3

-1-2 =-2 -3=-3

<em />

<em>2x - y = -4:</em>

2(-1)-(-2)=-4

(-2) -(-2)= -4

0=-4

arsen [322]

The zeros of the potynomial y = 3(x + 4)(x + 1)(x - 3)

$3(x + 4)(x + 1)(x - 3) = 0 \iff x+4=0\ \vee\ x+1=0\ \vee\ x-3=0\\\\x=-4\ \vee\ x=-1\ \vee\ x=3$

The park shown is in the shape of a square. Is the perimeter rational or irrational? Area = 24,200 yd 2

dangina [55]

Answer:

irrational

Step-by-step explanation:

A = s^2

s^2 = 24,200

$s = \sqrt{24200}$

$s = \sqrt{242 \times 100}$

$s = \sqrt{100 \times 121 \times 2}$

$s = 10 \times 11\sqrt{2}$

$s = 110\sqrt{2}$

P = 4s

$P = 4 \times 100 \sqrt{2}$

$P = 440 \sqrt{2}$

The perimeter is irrational.
