The price was marked down. If the price was reduced, we have to sum with the other value to find the original price:
The original price was $105.
The derivative of a variable raised to exponent of n, x^n is equal to the product of n and x raised to exponent of n-1.
d(x^n) = (n)(x^n-1)
So, from the given
d(9x + 5) = (1)(9x^1-0) + 5(0)
= 9
The given value of x is irrelevant to this item because the derivative does not contain any variable x.
Is the question complete or is that 0.25?
$ 45
multiply 60x.75 = 45
Answer:
is the LAsT one because 5x-1 can t be 0 so x doesn t have to be equal to 1/5 which would make 5x-1 =0.
