madreJ [45]3 years ago
7 0

Answer:

The cost of the mug is of $6.50.

Step-by-step explanation:

The cost of the mug and r refills is given by the following equation:

C(r) = 2.3r + 6.5

Cost of the mug:

The cost of the mug is found when no refills are bought, that is, C when r = 0, which is C(0)

C(0) = 2.3*0 + 6.5 = 6.5

The cost of the mug is of $6.50.

Write an expression for the sequence of operations described below. triple v, then subtract 7 from the result Do not simplify an
oee [108]

Given:

The sequence is defined as "triple v, then subtract 7 from the result".

To find:

The expression for the given sequence.

Solution:

Triple v means 3 times of v, i.e., 3v.

So, the result is 3v.

Then subtract 7 from the result. So, the expression for the sequence is

3v-7

Therefore, the required expression is 3v-7.

Assuming you mean

f(x) = 1/(x-3)

The domain is all numbers that x can take

This function is define except when the denominator goes to zero

x-3 cannot be zero

x cannot be 3

The domain is all real numbers except x=3
