Answer:
products - -3x and 6x^2
factors - 8 and 2x
Step-by-step explanation:
Answer:
A.)
In 2 months, Rex is 6 pounds and in 8 months he's 9lbs (from 2 to 8 is 6 months). So I inferred that to get to 9lbs from 6lbs is to go 0.5 pounds more each month.
B.)
2 = 6
3 = 6.5
4 = 7
5 = 7.5
6 = 8
7 = 8.5
8 = 9
C.) I don't think I can create a linear model here. So I don't think its nessesary.
D.)
If Rex were to grow over the expected 6 months, it would be 45.
To find the better buy we have to find the cost per pen for each.
1. 20 pens for $1.60 -> 1.60/20 = .08 cents per pen.
25 pens for $2.25 -> 2.25/25 = .09 cents per pen.
The best buy is 20 pens for $1.60 because it's cheaper per pen.
2. 13 berries for $2.60 -> 2.60/13 = .20 cents per berry
17 berries for $3.06 -> 3.06/17 = .18 cents per berry
The best buy is 17 berries for $3.06 because it's cheaper per berry.
