0.25 r – 0.125 + 0.5 r = 0.5 + r . Solve for r.

1 answer:

6 0

0.25r - 0.125 + 0.5r = 0.5 + r

0.75r - 0.125 = 0.5 + r |add 0.125 to both sides

0.75r = 0.625 + r |subtract r from both sides

-0.25r = 0.625 |divide both sides by (-0.25)

r = - 2.5

What is the birthday polynomial for 10/1/2006

zubka84 [21]

Answer:

Simplified version: 10x^5 - 1x^4 + 2x^3 - 6

Step-by-step explanation:

Since your birthday is 10/1/2006 we can use 1012006 as our digits.

We can make a random polynomial: 10x^5 - 1x^4 + 2x^3 + 0 x^2 + 0x - 6

(since 0 are meaningless we can simply this further into the below equation)

10x^5 - 1x^4 + 2x^3 - 6
