Number of people < (should be smaller than or equal to but I don't have that button on my keyboard) (100-7) / 15.50

103/15.50 = 6.64516...
You can't have .645 of a person, so you must round down. Therefore, she can bring 6 people including herself.

Hey there :)

f (x) = 5x² - 2x
g (x) = 3x² + x - 4

( f + g )( x ) is f ( x ) + g ( x )

5x² - 2x + 3x² + x - 4
Combine like-terms
5x² + 3x² - 2x + x - 4
8x² - x - 4

Your option will be the third option

KIM [24]

It is given in the problem that

Liam buys a motorcycle for $2,900

Its value depreciates annually at a rate of 12%=0.12

At the end of t years, it has a value of less than $2,000

The exponential equation modeling this situation can be written as below

$2900(1-0.12)^t$

The inequality representing its value less than $2,000 can be written as below

$2900(1-0.12)^t$
