Answer:
C
Step-by-step explanation:
The exact point should be (0, 4) if you're looking for the Y intercept. I'm assuming that each square represents one unit. Hope I could help.

these question is true
Answer:
1) The terminal side lies in quadrant 2
2) cosФ = -15/17
3) tanФ = -8/15
Step-by-step explanation:
1) First, we should realize that since sinФ = 8/17, it is positive. Thus, Ф must be in quadrants 1 or 2. And since cosФ is negative, Ф must be in quadrant 2 because cos, sin, and tan are all positive in quadrant 1
2) Next, we must realize that the sides given are a 8-15-17 right triangle. And in this case, since sinФ = 8/17, cosФ should be 15/17. But since cosФ is negative, cosФ = -15/17
3) Lastly, tanФ is opposite/adjacent. Since opposite of Ф is 8 and adjacent of Ф is 15, then tanФ should be 8/15, but since Ф is in quadrant 2, then tanФ is -8/15
Answer:
#1 is -9
#2 is 3
Step-by-step explanation:
-9x3 is -27 then add 10 to that you get -17
5x3 is 15 then subtract 1 and you get 14
Simple...
you have:
1.) x-3y when x=-4 and y=9
-->>> (plug it in)
-4-3(9)
-4-27
-31
2.) a-|b| when a=-7.6 and b=-8.9
-->>>(plug it in)
-7.6-|-8.9|
-16.5
3.) 3(8x-y) when x=-4 and y=9
-->>(plug it in)
3(8(-4)-9)
3(-32-9)
3(-41)
-123
4.)
when c=2 and d=
54
Thus, your answer.
