Answer:
y=5-2x
Step-by-step explanation:
2x+y=5
take 2x to the other side to make y the subject of the formula
y=5-2x.
y = -2x+5
Subtract 2x from each side
2x-2x +y=-2x+5
(fg)(x) = 6x³ - 2x² + 12x - 4
( f g ) ( x ) = f ( x ) * g ( x )
f(x) = 2x² + 4
g(x) = 3x – 1
( f g ) ( x ) = (2x² + 4) (3x – 1)
= 6x³ - 2x² + 12x - 4
x=4 y=5
if we put two pharases together
the answer is as follows pic :
x > -1
