Evaluate f(x)=5x- 9 at the given value of x. f(8) f(8)=

f(8) = 31

Step-by-step explanation:

To evaluate f(8) substitute x = 8 into f(x)

f(8) = (5 × 8) - 9 = 40 - 9 = 31

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
