Step-by-step explanation:
let the angle in 3rd quadrant be X
x+2=180
Answer: y= -4cos (pi/4x)-3
Step-by-step explanation:
Answer:
y=-2x
Step-by-step explanation:
Answer:
x = 4
y = 
Step-by-step explanation:
Ummmm
I'm not sure if this is corrrect but this is what I got
So first you solve 2x+4y=22 to find x
and you get x =
Then you have to subtitute
for
in 
which you then get y= 
After you have to subttitute y=
for y in x =
which you get as x=4
Finally you get the answer as:
x = 4
y =
