Steps:
1) 4,000 * .045 = 180
2) 180 * 6 = 1,080
3) 4,000 + 1,080 = 5,080

4)4,000 * .049 = 196
5) 196 * 6 = 1,176
6) 4,000 + 1,176 = 5,176
7) 5,176 - 5,080 = $96
Answer= $96

Larry has 4-cent stamps and 9-cent stamps, which he can combine to produce various amounts of postage. For example, he can make
Tju [1.3M]

Answer:

  • the largest number that cannot be made is 23
  • see below for an explanation

Step-by-step explanation:

<em>Why numbers greater than 23 can be made</em>

From any number that Larry can make that includes an appropriate number of stamps, Larry can ...

  • add 1 by adding 1×9 and taking away 2×4
  • add 2 by adding 2×9 and taking away 4×4
  • add 3 by adding 3×9 and taking away 6×4
  • add 4 by adding 1×4
  • add 5 by adding 4 and 1 (add 9, take away 4)
  • add 6 by adding 4 and 2 (add 2×9, take away 3×4)
  • add 7 by adding 4 and 3 (add 3×9, take away 5×4)
  • add 8 by adding 2×4
  • add 9 by adding 1×9

Clearly, for Larry to be able to continue adding any number, he must start with a number that contains at least 6×4 cents = 24 cents.

Larry can make 24 cents from 6 4-cent stamps. Using the above table, he can add any amount to that.

___

<em>Why 23 cannot be made</em>

For 23 cents, the number of stamps must include 0, 1, or 2 9-cent stamps, so there are 3 cases to try for making 23:

  • 23 cannot be made from 0 9-cent stamps because 23 is not divisible by 4
  • 23 cannot be made using 1 9-cent stamp, because 14 is not divisible by 4
  • 23 cannot be made using 2 9-cent stamps, because 5 is not divisible by 4.

Therefore, 23 cannot be made.

Y = x^2 + 10x - 171
y = (x - 9)(x + 19)

x - 9= 0 x + 19 = 0
x = 9 x = -19

Answer B covers all requirements... the factored form is
y= (x + 19)(x - 9)
and the zeros are -19 and 9
