You would substitute the given value of “y” into the equation of -14x+y=16
-14x+5x-2=16
Then you would solve for “x”
x=2
You would then substitute the value of “x” into the equation to solve for “y”
y=5(2)-2
Which would then give you a value for “y”
y=12
So the answer is (2,12)
Let's check.
x = 5π/24
4x = 5π/6
cos 4x = cos(5π/6) = cos 150° = -√3/2
cos² 4x = (-√3/2)^2 = 3/4
4 cos² 4x -3 = 4 (3/4) - 3 = 0
Answer: TRUE
Answer:
C
Step-by-step explanation:
ok so they want you to put everything but y on one side
to get rid of the -4, you add 4 to both sides
you are then left with
2/3y=x+4
multiple both sdies by 3/2
y= 3(x+4)/2
divide everything by 2
y=3/2x+6
C
