Hello,
x=R*cos(t)
y=R*sin(t)
y=2x+1
==> Rsin(t)=2Rcos(t)+1
==>R(sin(t)-2cos(t))=1
==>R=1/(sin(t)-2cos(t))
Answers in order top to bottom:
8
6
-8
__________
The equation can be simplified by dividing both sides by 2
remember, anything times 0 is 0.
4x + 3y = 24
Now plug in values
if x = 0;
4(0) + 3y = 24
3y = 24
y = 8, this is the first answer
if y = 0;
4x + 3(0) = 24
4x = 24
x = 6, this is the second answer
if x = 12;
4(12) + 3y = 24
48 + 3y = 24
3y = -24
y = -8, this is the third answer.
Just write them the on the other side the exact same way that they are on the Y coordinate hope this helps:)
Answer:
3.9
Step-by-step explanation:

-2/9-1/3=-5/9 5/9 has to be spaced between 7 spots. Since C is fourth one, -2/9+4(5/63)=-2/9+20/63=-14/63+20/63=6/63=2/21 So H.
