Given:
Christopher scores 2 goals in a soccer game.
His goal total can vary from the average by 1 goal.
To find:
The absolute value equation can be used to calculate Christopher's maximum and minimum goals per game.
Solution:
Let Christopher scores x goals in a soccer game.
Then difference between actual goals and average goals is x-2.
His goal total can vary from the average by 1 goal.
Maximum number of goals = 2+1 = 3
Minimum number of goals = 2-1 = 1
It means, the difference between actual goals and average goals is either -1 and 1.
...(1)
...(2)
Using (1) and (2),we get
Therefore, the correct option is C.
Answer:
Last option: 4
Step-by-step explanation:
The quadratic equation simplified: has the form:
In this case, you can identify that "a", "b" and "c" are:
To solve this quadratic equation by completing the square, Carlos should add to both sides of the equation. This is:
Then:
Therefore you can observe that the number he should add to both sides of the equation is: 4
