Answer:
y/2 = 4.5
Step-by-step explanation:
1/4x + 2y = 11/4
distribute by 4 to eliminate fractions
x + 8y = 11
+ <u>-x - 6y = 7</u>
2y = 18
y = 9
half of 9 = 4 1/2
Step-by-step explanation:
note that
sin²x = (1-cos²x)
LHS= cos²x - 2 sin²x
= cos²x - 2(1-cos²x)
= cos²x - 2 + 2cos²x
= 3cos²x - 2
or
cos²x = (1-sin²x)
LHS= cos²x - 2 sin²x
=1-sin²x - 2 sin²x
= 1-3sin²x
Answer:
UR in trouble
Step-by-step explanation:
Look, the First order is the biggest force in the galaxy.
Now, it is gonna send a star destroyer to ur house and blow it up.
Answer:
