3) Add the values on the same side of equality:
4) Pass the 8 to divide:
Answer:
The value of x is given by:
Question 3:
For this case we have the following equation:
The ordered pair solution is the one that satisfies both sides of the equation.
For the point (6, 2) we have:
Substituting values we have:
We observe that both sides of the equation are equal.
Therefore, the ordered pair solution is (6, 2)
Answer:
An ordered pair that is a solution of the equation y = x-4 is:
(6, 2)
Given:
The equation of a quadratic function is:
To find:
The equation of the axis of symmetry for the given function.
