Since the percent lost per hour is constant, this is a linear equation, and the slope-intercept form of a linear equation is:
Where <em>m</em> is the slope and <em>b</em> is the intercept.
In this case, we want to formulate how much percentage is left based on how many hours have passed, so the percent left is dependent upon the time passed. This means that the dependent quantity is the percent of battery life left, and this will be variable <em>y</em>.
Because they don't have the same answer
Answer:
Rewriting the equation in the form (x+c)²=d by completing the square
The solutions to the quadratic equation are:
Step-by-step explanation:
Given the equation
subtract 22 from both sides
simplify
Rewriting the equation in the form (x+c)²=d by completing the square
solve
also solving
Therefore, the solutions to the quadratic equation are:
