Ana used 49 strawberries to make 7 strawberry smoothies. She used the same number of strawberries in each smoothie. How many strawberries did Ana use in each smoothie?

7 strawberries

Step-by-step explanation:

To find out how many straberries Ana used in each smoothie we need to take the total amount of strawberries she had and divide it by the amount of smoothies she made. So we need to follow this equation:

Strawberries in each smoothie = total strawberries/ smoothies made

Strawberries in each smoothie = 49/7

Strawberries in each smoothie = 7 strawberries

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
