Answer:
Find the coordinates of the point of intersection of the axis and the directrix of the parabola whose focus is (3,3) and directrix is 3x−4y=2. Find also the length of the latus-rectum.
Step-by-step explanation:
1. a=h(b+c)
2. distribute the h:
a=hb+hc
3. move the 'hb' to the left:
a - hb = hc
4. subtract the a from both sides:
-hb = hc - a
5. divide both sides by -h to isolate b:
b = -hc+a/h

If 75% liked skating, then 25% did not
so 25% of what is 35
0.25x = 35
x = 35/0.25
x = 140...so there is a total of 140 students
75% of 140 =
0.75(140) = 105...so 105 students liked skating
