Answer:

x = -2/y -1

Step-by-step explanation:

2xy + 4 = -2y -----> x = -2y -y

Step 1: Divide 2y to all sides. 2xy÷2y + 4÷2y= -2y÷2y. Since we are divinding y with y it cancels out, so it will be -2÷ 2 = -1

Step 2: x + 2y = -1

Step 3: Then subtract 2y and move it to the other side.

x = -2/y -1

Another way of explaining it:

2xy + 4 = -2y

Step 1: Divide 2 to all sides. 2xy÷2 +4÷2 = -2y÷2

Step 2: xy + 2 = -y

Step 3: Subtract the 2 and move it to the other side.

xy + 2 = -y

-2. -2

Step 4: xy = -2 -y

Step 5: Then we divide the y to all sides. xy÷y = -2÷y - y÷y

Step 6: xy÷y = -2 ÷ y -2 ÷y. We're trying to get x by itself.

Step 7: x = -2/y -1. Since we are divinding y with y it cancels out, so it will be

Answer: x = -2/y -1

Find the equation of a circle with the same center as the circle in the graph above and that passes through a point 2 units away

Ira Lisetskai [31]

The equation of a circle with center at (a, b) and radius, r, is given by
$(x-a)^2+(y-b)^2=r^2$

The given circle in the graph has the center at (0, 2) with the radius of 1 units.

<span>A circle with the same center as the circle in the graph and that passes through a point 2 units away from the given circle has its center at (0, 2) and a radius of 3 units.

Thus the equation of the circle is given by
$(x-0)^2+(y-2)^2=3^2 \\ \\ x^2+y^2-4y+4=9 \\ \\ x^2+y^2-4y-5=0$ </span>
