(f+g)(x)=f(x)+g(x) = x³-x +x³ +2x²-10=2x³ + 2x²-x-10
(f+g)(x)=2x³ + 2x²-x-10
10.
42-22 is 20
20 minutes divided by 2 minutes is 10
Answer: Reflexive Postulate
Any number or expression that is equal to itself is due to the reflexive postulate of equality. Think of a mirror and how it gives a reflection. That's one way to remember. It might seem like a silly idea, but it's useful in geometry settings among other places as well.
Answer:
y=-4x+3
Step-by-step explanation:
4x + y=3
4x gets switched to the other side so that it is by its self
which then the equation is going to be y=-4x+3 bc the sin changes
