the first choice
Explanation:
The reason why it is the first choice is because you would need to experiment twice before concluding your experiment one has to be normal height and the second test has to be higher also the mass on the car also is a factor to the experiment.
Inequalities are used to represent unequal expressions.
The solution set to
is: 
The inequality is given as:

From the inequality above, we have the following observation.
- The value of variable x starts from 7/16 (inclusive)
- The value of variable x has no end (i.e. infinity)
Because, 7/16 is inclusive of the values of x, we make use of the open square bracket i.e. [
We treat
, as an exclusive value. So, we make use of the close parenthesis i.e. )
Hence, the solution set is:

The rule used to translate the image is
.
In this question we are going to speak of point translations. Vectorially speaking, a translation between two points is defined by this expression:
(1)
Where:
- Original point.
- Translation vector.
- Translated point.
If we know that
and
, then the translation vector is:



Therefore, the rule used to translate the image is
.
