Find an equation for y in terms of x

snow_tiger [21]

Answer:

y = $\frac{9}{x^2}$

Step-by-step explanation:

Given y is inversely proportional to x² then the equation relating them is

y = $\frac{k}{x^2}$ ← k is the constant of proportion

To find k use an ordered pair from the table

Using x = 3 when y = 1 , then

1 = $\frac{k}{3^2}$ = $\frac{k}{9}$ ( multiply both sides by 9 )

9 = k

y = $\frac{9}{x^2}$ ← equation of proportion

Find the area of a square with side length 3/4 yard

Roman55 [17]

The area of square with side of 3/4 yards is 9/16 square yards

Step-by-step explanation:

The formula for area of square is given by:

$Area = s^2$

where s is the side of the square

Given

Side of square = s = 3/4 yards

So,

$Area = s^2\\= (\frac{3}{4})^2\\=\frac{9}{16}$

Hence,

The area of square with side of 3/4 yards is 9/16 square yards
