The piecewise function describes a newspaper’s classified ad rates. y = {25 when x≤4
25 + 5 (x − 4) when x > 4

a) Interpret this piecewise function (describe in words what it means) (2 points)

Find the cost of a 3 line ad (2 points)

Find the difference in cost between a one and four line ad (2 points)

Find the cost of a seven line ad (2 points)

7

step-by-step explanation:

yuo ned the activity or vertical angle of the form of 1,7 but 2,2 has a c4,2 as it verticie so i not have a car

20%

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
