Sorry I'm a bit late but the answer would be c as zero would indicate the time in which the egg is 0 ft above the ground making the egg at ground height
Rise=16, run=7. Slope is rise/run, and therefore is 16/7. The run is considered to be the x coordinate. Since the x coordinate on the point is 21, we know it has moved 3 exact points away from the origin (21/7=3). We can use this movement of 3 exact points to determine the y coordinate as well. Since the rise (y) is 16 for every exact point on a graph, we know the graph has risen 48 units (16x3=48). So, the point ends up being (21,48). The rate of change is 16cm per 7 minutes, or 2.28cm/minute. The equation is Y=(16/7)X (no y intercept because the graph starts at the origin). The equation gives you the y value of 48 when x is equal to 21.
Jack had b boxes. Then he got 4 more. That is equal to:

On Wednesday, half the boxes were destroyed. To find half the amount, you can divide by 2, which is equal to:

Choice C matches the answer. Your answer is C
Answer:
A. 6
Step-by-step explanation:
There are 3 pairs of side midpoints which you can draw a line of symmetry, and 3 pairs of vertices that you can use as a line of symmetry. This is a total of 6. Hope this helps!
