ANSWER
A.) The graph of f(x) is horizontally compressed.
EXPLANATION
The given absolute value function is
The parent function is
Since the factor -6 has an absolute value greater than 1, the graph of the given function will be narrower than the graph of the base function.
Hence the graph is horizontally stretched by a factor of 6.
The graph opens downwards because of the negative sign.
It has vertex at (-5,-2)
It is given in the question that
Anna buys 12 pens and 20 pencils for a total cost of $16. One pen costs $0.40 more than a pencil.
Let the cost of pencil is $ x .
Therefore cost of pen is
According to the question
Distributing 12 and combining like terms, we will get
Therefore cost of pencil is $0.35 and cost of pen is
