Answer:
<h2>x³ + x² - 3x - 3</h2>
Step-by-step explanation:
I'm assuming g*f means g times f, so you want to multiply the two functions together.
(x² - 3)(x + 1) Since the product is 2 binomials, use FOIL
= x²(x) + x²(1) - 3(x) - 3(1)
which simplifies to
<h2>x³ + x² - 3x - 3</h2>
Answer:
$1,100
Step-by-step Explanation:
Dee Wallace's salary in 2006 = $61,000 Dee Wallace's salary in 2009 = $64,300
The salary increased in => 2009 - 2006 = 3yrs
The amount of salary increased = 64,300-61000 = $3,300
The annual change of salary = 3,300/3 = $1,100
Answer:
37/50
Step-by-step explanation:
because 37% is out of 100
Set up 2 proportions
562.5 over 12.3 = x over 1
and
353.6 over 8 = x over 1
then cross multiply both of them
12.3x = 562.5
and
8x = 353.6
then divide both of them
round
x = 45.73
and
x = 44.2
based on those answers the petersons were driving faster
