A pair of intersecting planes and where they intersect

Two planes always would intersect at a line, as shown in attached figure below.

Step-by-step explanation:

As we know that

A plane has basically 2 dimensions.

But as the plane is infinitely large, we can say that length and width of a plane is not supposed to be measured. (can not be measured)

Let suppose we have a pair of intersecting planes.

If If two intersecting planes are not parallel, then they would intersect each other somewhere.

BUT

Two planes always would intersect at a line, as shown in attached figure below.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
