140 pages
1/3 of 300 is 100pages
20% of 200 (remaining pages) is 40
100 + 40 = 140
If you had
ax^2+bx+c
a is the leading term
when a>0, the parabola opens up and therfor has a minimum point and no max since it goes up infinitely
when a<0, the parabola opens down and therefor has a maximum point and not min since it goes down infinitely
-x^2+8x+9
-1<0
opens down
has max
vertex=max
Answer:
I'm not going to give you an exact answer because there could be many different ones
Step-by-step explanation:
The equations can be rewritten as:
2x - 7 = 7y
-4x + 19 = 3y
then you just insert a value for x and get the answer.
Answer:
15/17
12/37
12/13
20/21
Step-by-step explanation:
5)
cos A = adj/hyp = 15/17
6)
cos C = adj/hyp = 12/37
7)
cos Z = adj/hyp = 36/39 = 12/13
8)
tan A = opp/adj = 20/21
