Step-by-step explanation:
B. (0, 50) y=50
C. y=mx+b y=25x+50
D. y=25(20)+50 y=500+50 y=550
Y=2x+320
x being the number of years and 320 being the initial population of mice
Hi there!
You can use distributive property to solve this equation.
These are the list of terms you have to multiply :
a × a² = a³
a × -ab = -a²b
a × b² = ab²
b × a² = a²b
b × -ab = -ab²
b × b² = b³
add all of those terms...
a³ - a²b + ab² +a²b -ab² + b³
simplify by adding like terms... (- a²b + a²b , ab² - ab²)
a³ + b³
Hope this helped!! :)
