How would I solve the equations: y = x-4 and y=x^2-4x using substitution

Mathematics

Answer:

x = 6

Explanation:

y = x - 4

26 = 4x + y


If y = y, then we can rewrite this system as this: 4x + x - 4 = 26


Then we combine like terms and add 4  on both sides to give us  5  x  =  30 . Divide by 5 on both sides and we arrive at the solution: x = 6

Find the exact value of : cos(2 arctan(4/3))
QveST [7]
Cos(2 arctan(4/3)) = cos(2 arccos(3/5)) = cos^2(arccos(3/5)) - sin^2(arccos(3/5)) = cos^2(arccos(3/5)) - sin^2(arcsin(4/5)) = (3/5)^2 - (4/5)^2 = 9/25 - 16/25 = -7/25.
