Someone please help , how do you solve this ?
The function f(x) = 1.50x + 12.50 relates how much Kelsey pays for digital service, f(x), to the number of movies, x, she streams in a month. What is the value and meaning of f(18)?
$27.00; this is the amount Kelsey pays for 18 months of service
$27.00; this is the amount Kelsey pays for 18 movies in 1 month
$39.50; this is the amount Kelsey pays for 18 months of service
$39.50; this is the amount Kelsey pays for 18 movies in 1 month

Best ResponseYou've already chosen the best response.1the x intercept is the value of x when y = 0 and y intecept is value of y when x = 0 so to find the x intercept solve for x : 3x  2(0) = 18 3x = 18 x = ?

Best ResponseYou've already chosen the best response.0Hey sorry that was the wrong question because it dosnt make sense it's ... The function f(x) = 1.50x + 12.50 relates how much Kelsey pays for digital service, f(x), to the number of movies, x, she streams in a month. What is the value and meaning of f(18)?

Best ResponseYou've already chosen the best response.1wrong. You are multiplying the 3 to x. So you have to divide to get rid of it: \(\sf\Large \frac{3x}{3}=\frac{18}{3}\)
