Reggie is making a double-layer cake the recipe for the first layer calls for 2 1/4 cups of sugar. the recipe for the second layer calls for 1 1/4 cups of sugar reggie has 5 cups of sugar. how much will he have left after making both recipes

1 1/2

Step-by-step explanation:

Add 2 1/4 and 1 1/4 to get 3 2/4 or 3 1/2.

Subtract 5-3 1/2

5-3.5=1.5 or 1 1/2

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

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8
