Use the change of variables s=x+3y, t=y to find the area of the ellipse x2+6xy+10y2≤1.

MArishka [77]

$t=y\implies s=x+3t\implies x=s-3t$

Then

$x^2+6xy+10y^2=(s-3t)^2+6(s-3t)t+10t^2=s^2+t^2\le1$

which is a disk of radius 1, hence with area $\pi$ .

Write an expression for the number of yards in f feet

koban [17]

1 yard = 3 feet

Then the to find the number of feet in a number of yards use the conversion factor, 1 = 3 feet / yard

number of feet = number of yards * 3 feet/yard

If the number of feet is f and the number of yards is y, you can write the expression in this way:

f = 3y
