kaheart [24]

Alice should buy 1.36 kilograms of veal.

Step-by-step explanation:

Given,

According to store's scale;

1 pound = \frac{1}{2.20}\ kg

As Alice wants to buy 3 pounds, therefore,

3 pounds = \frac{1}{2.20}*3\\

3\ pounds = \frac{3}{2.20}\\3\ pounds = 1.36\ kg

Alice should buy 1.36 kilograms of veal.

Point D is the image of D(-2,1) under a reflection across the x-axis. What are the coordinates of D?
vredina [299]

Answer:

(-2,-1)

Step-by-step explanation:

To reflect something across an axis we need to change the coordinate of the other axis.  To reflect a point across the X axis we need to change the sign on  the Y axis because that will put it on the other side of the X axis.  In this question the 1 is what we will change from positive to negative.  By doing this it will move the point from above the X axis to below the X axis.

I hope this helps and please don't hesitate to ask if there is anything still unclear!
