Answer:
D
Step-by-step explanation:
For a function in the form f(x) = x, we can say:
- the function f(x) = ax is a vertical stretch if a>1 and compress if 0<a<1
- the function -f(x) is the original, flipped over x-axis
<em>keeping the 2 rules in mind, we can say that</em>
<em>vertical stretch by a factor of 3 would make it f(x) = 3x</em>
<em>Then</em>
<em>flip over x-axis would make it f(x) = -3x</em>

Answer:
Mr.Smith paid $29.4.
Step-by-step explanation:
Mr.Smith paid $24.5 plus additional 20% of $24.5, and to figure out the total amount that he paid, we need to know what is 20% of $24.50.

.
Mr.Smith paid additional $4.9; therefore, the total amount he paid was
$24.5 + $4.9 = $29.4.
Mr. smith paid $29.4.
