Answer:

money owed (in order): $850, $870.40, $891.29, $912.68

Step-by-step explanation:

The formula is

money owed = amount owed the previous week + amount owed previous week × interest rate (in decimal form)

so thats:

money owed = amount owed the previous week + amount owed previous week × 0.024

we can simplify that to:

money owed = amount owed the previous week x (1.024)

after 0 weeks:

$850 (just started, no interest added)

after 1 week:

$870.40

after 2 weeks:

$891.29

after 3 weeks:

$912.68

If you add 15 to 3 times the mystery number you get 78 was the mystery number
andreyandreev [35.5K]
So the equation looks like this : 15*3x=78
subtract 15 from both sides:        -15      -15
then divide by 3 from both sides
to isolate the variable:                  3x=63
                                                      3/3x=63/3
                                                        x=21 (your mystery number is 21)

If f(x)=5x^4+3, then what is the remainder when f(x) is divided by x-1?
KatRina [158]
8


This is actually fairly simple. If you take the x-1 and set it equal to 0 you get 1. And if you plug that value into the x you get 8, which is the remainder. This is called the remainder value theorem.
