Mike is a veterinarian. He is placing a nine-line job ad for an assistant. The following piecewise function gives the price of an x-line ad. a(x) = 45 when I <3
= 45 + 9(x – 3) when I > 3
a. The difference between the cost of a two-line ad and the cost of a 3-line ad is
b
The cost of a 10-line ad is $
c
The cost of an 11-line ad is
d. Can you find the difference between the cost of a 15-line ad and a 17-line ad, without finding out the cost of each ad first?

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
