Answer:

  see attachment

Step-by-step explanation:

It is convenient to use a spreadsheet for this purpose.

The first row of numbers is constant at $45, as there is no daily charge associated with that payment method.

The second row of numbers uses the formula ...

  cost = $12 + $4×(number of days)

The third row of numbers uses the formula ...

  cost = $6×(number of days)

___

Of course, you can use these formulas to fill in the numbers by hand. For example, for 15 days, the charges are ...

  • Early Pay: $45 (no calculation necessary)
  • Deposit Plus: $12 + $4×15 = $12 +60 = $72
  • Daily Pay: $6×15 = $90

The number w and 0.8 are additive inverses.
umka2103 [35]

Since, the number w and 0.8 are additive inverses.

A number 'a' is said to have an additive inverse '-a' if "a+ (-a)= 0".

Since, 'w' and '0.8' are additive inverses of each other such that w + 0.8 = 0

Therefore, the value of 'w' should be '-0.8' so that -0.8 + 0.8 = 0.

So, the value of 'w' is =0.8

Now, Refer to the attached image which represents the position of 0.8 , w ( that is -0.8) and the sum of 0.8 and w.

Sum of 0.8 and w = 0.8 + w

= 0.8 +(-0.8)

= 0.

Let the function f be defined as f(x)= 5x^2 - 7(4x+3). What is the value of f(3)
Katen [24]

Answer:

f(x) = -60 is your answer

Step-by-step explanation:

Plug in 3 for x

f(x) = 5x² - 7(4x + 3)

f(x) = 5(3²) - 7(4(3) + 3)

Follow PEMDAS. First, solve the parenthesis

3² = 9

4(3) + 3 = 12 + 3 = 15

f(x) = 5(9) - 7(15)

Multiply

f(x) = 45 - 105

Simplify. Subtract

f(x) = 45 - 105

f(x) = -60

f(x) = -60 is your answer
