ANSWER
The correct answer is C .
<u>EXPLANATION</u>
We have
and
.
We solve the two equation simultaneously by elimination method. We need to be smart and eliminate y, since we are looking for .
We first multiply equation (2) by 2
.
We add equation (3) and (1).
.
Dividing through by 6 gives
.
The interpretation of the function is that the difference y between the car's actual speed x and the displayed speed is 8
<h3>How to describe the translation. </h3>The function is given as:
y = |x - 8|
The above function is an absolute function.
And the parent function of an absolute function is
y = |x|
When a function is translated right by h units, the new function is y = |x - h|
This means that the translation is a translation to the right by 8 units
See attachment for the graph the function.
<h3>Interpret the function and the translation in terms of the context of the situation.</h3>The function is given as:
y = |x - 8|
This represents the difference y between the car's actual speed x and the displayed speed.
So, the interpretation of the function is that the difference y between the car's actual speed x and the displayed speed is 8
