Mary need 3/1/3 yards of red fabric 2/2/3 yards of yellow fabric and 4/2/3 yards of white fabric of make a quilt. she wants to make a 4 quilts. How many yards of each fabric does she need . Drag the numbers completed answer

Of red fabric:

Of yellow fabric

Of white fabric

Step-by-step explanation:

Proportions

We use proportions when the magnitudes involved in the solution of a problem depend on each other by a fixed factor. If X and Y are proportional, then X=k.Y, where k is any constant different from 0.

We have the amount of fabric Mary needs to make a quilt:

If Mary wanted to make 4 quilts, she would need 4 times each amount of fabric:

Of red fabric:

Of yellow fabric

Of white fabric

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
