Step 1: Replace y in the second equation with the right side of first equation like that:
x+4=-2x-2

Step 2: Solve that simple equation:
x+4=-2x-2
x+2x=-2-4
3x=-6
x=-6/3=-2

Step 3: Replace x of first equation with found value and solve it:
y=-2+4
y=2

So, the solution is: x=-2 and y=2.

lozanna [386]

Answer:

The circle's diameter is 4\ yd

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=\pi D

where

D is the diameter of the circle

In this problem we have

C=12.56\ yd

\pi=3.14

substitute the values and solve for D

12.56=(3.14)D

D=12.56/(3.14)=4\ yd
