Answer:
False
Step-by-step explanation:
4 cos^4 (4x)-3 = 0
Substitute into the equation
4 cos^4 (4pi/24)-3 = 0
4 cos^4 (pi/6)-3 = 0
Take the cos pi/6
4 ( sqrt(3)/2) ^4 -3 =0
Take it to the 4th power
4 ( 9/16) -3 =0
9/4 -3 =0
9/4 - 12/4 = 0
-3/4 =0
False
Answer:
Step-by-step explanation:
I will use substitution
We will substitute the answer for y into the bottom equation
x+(4x+3)=-2
5x+3=-2
5x=-5
x=-1
Now solve for y
(-1)+y=-2
y=-1
Write as an ordered pair
(-1.-1)
