This is the required formula.
Ervin sells 13 cars per 3 months so 13/3=4.3 cars per month.
this means that
___month___ ___cars sold___
1 4.3
2 2*4.3
3 3*4.3
: :
n n*4.3
the linear function representing the cars sold per month is f(n)=4.3*n
(Practically, this means that the expected number of cars sold after n months is a whole number close to 4.3*n.)
Answer:
the slope is 4.3 (13/3)
Answer:
-y² - 4y - 6
Step-by-step explanation:
Step 1: Write expression
5y² - 6y - 11 - 6y² + 2y + 5
Step 2: Combine like terms (y²)
-y² - 6y - 11 + 2y + 5
Step 3: Combine like terms (y)
-y² - 4y - 11 + 5
Step 4: Combine like terms (constants)
-y² - 4y - 6
