4. Elizabeth has organized a set of cards from greatest to least. However, she has made a few mistakes. Identify which numbers are not in the correct location. Then, rewrite the cards in the correct order.

3/2, 5/4/, 7/10, -1/4, -13/20, -2/3

Step-by-step explanation:

3/2= 1.5 which is the greatest,

5/4 = 1.25 which is second greatest,

7/10 = 0.7 which is third greatest,

-1/4 = -0.25 which is fourth greatest,

-13/20 = -0.65 which is fifth greatest,

-2/3 = -0.666666 (repeating) which is least greatest

Step-by-step explanation:

You can be fooled by this question. Be careful of it. There are two equations that satisfy one of the conditions.

y = -(x - 2)^2 + 3  and   y = -x^2 + 7

But you have to take the second condition into consideration.  The vertex is at 0,7

Only one of them satisfies that condition. y = -x^2 + 7 This one has a maximum (a vertex) at x = 0 and y = 7

The vertex of the other equation is at (2,3)
