Answer 1

Answer:

Answer:

Relation

Explanation:

The definition of a relation is just a set of ordered pairs.

A function is a relation in which each domain element is paired with exactly one range element.

It can't be a function because if it is a vertical line, then the x-value is the same for the whole line.

$ax - b < c$

Add sides b

$ax - b + b < c + b$

Simplification

$ax < b + c$

Divide sides by a

$(a)/(a) x < (b + c)/(a) \n$

$x < (b + c)/(a) \n$

it takes 1 gallon of diesel 1 fuel for a cruise ship to trarel 6 inches how many gallons will it take for the cruise ship to travel 1 mile

Answers

The last cruise I went on had a cocktail party for returning guests, which the captain attended to participate in a question and answer conversation. One of the questions asked pertained to the amount of fuel a cruise ship uses. I can't remember everything that was said, but I do remember the captain saying one gallon of fuel moved the ship a mere 17 inches!! So I would imagine close to a thousand gallons of fuel would be needed to move the ship one mile..

Answers

f(x)=9x³+2x²-5x+4
g(x)=5x³-7x+4

f(x)-g(x)=(9x³+2x²-5x+4)-(5x³-7x+4)=
=9x³+2x²-5x+4-5x³+7x-4=
=(9x³-5x³)+2x²+(-5x+7x)-4=
=4x³+2x²+2x-4

Answer; f(x)-g(x)=4x³+2x²+2x-4
