Answer:
Step-by-step explanation:
Let b be the number of stamps Bria has and m be the number of stamps Matt has.
Given : Bria and Matt have a total of 400 stamps.
i.e. No. of stamps Bria has + No. of stamps Matt has = 400
i.e. In terms of variables (1)
Also, Matt has three times as many stamps as Bria.
i.e. No. of stamps Matt has = 3 x (No. of stamps Bria has )
i.e. In terms of variables (2)
From (1) and (2) , the system of equations can be used to find the number of stamps Bria has, b, and the number of stamps Matt has, m will be :_

Answer:
To make f continuous at ,
should be defined
Step-by-step explanation:
A function, let say , is defined at
is continuous at
If the limit of as
approaches
is equal to the value of
at
.
Mathematically it is written as:
if
then
is continuous at
.
So from the above definition, we conclude that:
To make f continuous at ,
should be defined
i.e.
if
then
