3x - 2 - (2x + 1)
<u><em>Distribute -1 to both terms in the parentheses.</em></u>
3x - 2 - 2x - 1
<em><u>Combine like terms.</u></em>
x - 3
Thus, D is your answer.
Ok first I call the slope gradient
The gradient is
rise / run
This means
The change in the y value over two points/
The change in the x value over two points
eg
(3,5) (6,7)
Let’s say I took those two points out of my graph
Then the gradient is
7-5 / 6-3
Rise/run
Which is
2/3
Now let’s the the same with yours
Choose two points on your graph and do the same

The function for the amount saved if they purchase a used drone rather than a new drone from Jim's store is f(x) = 0.45x
He sells used drones at 70% of the price (x).
So, the selling price of a used drone is:
Express percentage as decimal
Also, he sells new drones at 15% more of the price (x).
So, the selling price of a new drone is:
Express percentage as decimal
The amount saved is the difference between the prices of the drones.
So, we have:
This gives
Subtract
Express as a function
Hence, the function for the amount saved is f(x) = 0.45x

<span>Given:
Price = 2$ per square foot</span>
Total price = $288
<span>Find:
The length of the floor in feet.</span>
Solution
Squares have sides of
equal length. The solution for the area of a square is:
<span>Area = x2</span>
where x is the side
length.
If each square foot
is $2 and the total is $288, we divide 288 by 2 to find out how many
square feet the floor has.
$288 / ($2 per square
foot) = 144 square feet
Take the square-root
of this value to get the length of the floor.
x = √144
x = 12
<span>Therefore, the length
of the floor is 12 feet.</span>
