Step-by-step explanation:
90° ± 90° = 180°
180° - 50° = 130°
130°
1-8sin^2 Acos^2A or 1-8sin^2A
Answer:
Y = 1/4x-1
X = 4y-1
Step-by-step explanation:
layout the equations :
x+1/y = 4 y+1/x = 1/4
solve the equations, remember to switch sides switch signs solving the equations will give us the value of the letter
x+1/y = 4
x+1 = 4y
x=4y-1
***
y+1/x = 1/4
y+1 = 1/4x
y = 1/4x-1
Answer:
-1
Step-by-step explanation:
2(.5n-3)=n-0.25(12-12n)
first you distribute whatever is on the outside of the parenthesis to the inside of the parenthesis
1n-6=n-3+3n
then you combine like terms and end up with
1n-6=-3+4n
add 6 to each side to get
n=3+4n
subtract 4n from each side to get
-3n=3
divide -3 from each side to get
n=-1
