Answer:
Option A) Combined, with a saving of x-y cents
Step-by-step explanation:
We are given the following in the question:
The rate to mail a package is x cents for first pound and y cents for each additional pound.

Weights of packages =
3 pounds and 5 pounds
Cost of combined package:
Total weight = 8 pounds

Cost of sending separately:

Difference between cost of sending the packages separately and combined

Thus, sending the packages combined is a cheaper method with a saving of (x-y) cents
Thus, the correct answer is:
Option A) Combined, with a saving of (x-y) cents
Answer:
The graph in the attached figure
The point (-1,4) represent a solution
Step-by-step explanation:
we have
----> inequality A
----> inequality B
using a graphing tool
The solution is the shaded area
see the attached figure
Remember that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area of the solution of the system of inequalities
The point (-1,4) represent a solution
Answer:
B(7,10)
Step-by-step explanation:

(x+1)^2
(x+1)(x+1)
x^2+x+x+1
The expression is x^2+2x+1
And the answer is simple too : )
Second table :- y/x= 3 /2 so K = 3/2
Third table:- y/x = 117 and K = 117
