two boxes of apples contain a total of 24 apples. if you halve the number of apples in the first box and add 4 apples to the sec
2 answers:
Answer:
16 in first and 8 in second
Step-by-step explanation:
Let the number of apples be x in the first box then the number in the second box will be 24-x
if we half the number of apples in first box we get
And we add 4 apples in the second box we get
Since the apples in the two boxes were 20 we get
After simplification we get:
x=16
Hence, number of apples in first box were x that is 16
And number of apples in second box were 24-x that is 24-16 is 8

Check the picture below.
now, we know the directrix is at y = 1, and the focus point is at 1,3, well, notice the picture, the distance between those fellows is just 2 units.
the vertex is half-way between those fellows, therefore, the vertex will be at 1,2.
the distance "p", from the vertex to either the directrix or focus, is really just 1 unit. Since the focus point is above the directrix, is a vertical parabola, and it opens upwards, like in the picture, and since it opens up, the "p" value is positive, or +1.
