The circumference of a circle is equal to pi times the diameter.The direct variation equation represents this situation is <u>c=πd</u>

Step-by-step explanation:

Direct variation states that:

if ,y∝x

then the equation is in the form of:

y=kx

where, k is the constant of variation.

As per the statement:

c=π × d

c=πd

The circumference(C) of a circle is equal to pi times the diameter(d) then

c=π × d

c=πd

Therefore, the direct variation equation represents this situation is,

c=πd

Answer:

5x^2 + xy + 20

Step-by-step explanation:

Begin with 5x^2+3xy+12, Subtracting 2xy yields 5x^2 + xy + 12. Next, subtracting -8 yields 5x^2 + xy + 12 - (-8), or 5x^2 + xy + 20
