Caroline has a movie card worth $75 that her grandfather gave to her for her birthday. after seeing her first movie, the card’s value is $67. after she sees a second movie, its value is $59 and after she sees a third movie, its value is $51. assuming the pattern continues, which function ƒ(m) can be used to determine the amount of money on the card after m movies?

f(m) = 75-8m

Step-by-step explanation:

She began with $75.  After the first movie, she had $67 remaining; this means she spent

75-67 = $8

After the second movie, she had $59 remaining; she spent

67-59 = $8

After the third movie, she had $51 remaining; she spent

59-51 = $8

Each movie costs $8.  Letting m represent the number of movies, this gives us 8m.

Since she is spending money, we subtract this from the original amount, $75; this gives us

f(m) = 75-8m

f

step-by-step explanation:

f

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
