The diamond shape is formed when you graph these coordinates.
You can factor a parabola by finding its roots: if

has roots
, then you have the following factorization:

In order to find the roots, you can use the usual formula

In the first example, this formula leads to

So, you can factor

The same goes for the second parabola.
As for the third exercise, simply plug the values asking

you get

Add 3 to both sides:

Divide both sides by 1.5:

Answer:
A. v= $3,995.72 - $1,838.03
Step-by-step explanation:
Given:
fixed expenses: $1,838.03
total expenses: $3,995.72
We need to find the amount of Variable expense (v).
Now We know that;
Variable expense (v) can be calculated by Subtracting Fixed expense form Total expense.
framing in equation form we get;
Variable expense (v) = total expenses - fixed expenses.
Variable expense (v) = $3,995.72 - $1,838.03 = $2,157.69
Hence The equation represents Jessie's variable expense (v) = $3,995.72 - $1,838.03
Answer:
B(75) represents the percent of battery full after 75 minutes of game play
Step-by-step explanation:
Let m represent the number of minutes of game play. If 1% of the battery is drained every five minutes of game play, then after m minutes of game play
was drained.
The battery starts off at 80% full. After m minutes the battery will have

percent full.
When
minutes, then
