Answer:
The solution for given system of equation is: 
and ordered pair is: 
So, (1,3) is not solution to the given system of equations.
Step-by-step explanation:
we can solve the system of equations to find the value of x and y and then verify if (1,3) is a solution or not.
The system of equation given is:
Solving:
Let:
Put value of y from equation 2 into equation 1
Now, put value of x in equation 2 to find value of y
So, the solution for given system of equation is: and ordered pair is:
So, (1,3) is not solution to the given system of equations.
Answer:
82/43 = 1 and 39/43
Step-by-step explanation:
When dividing 82 by 43 , the operation follows;
82/43 = 1 and 39/43
This means the quotient is 1 and reminder is 39
However;
82/43 = 1.907 ------nearest whole number is 2.
so the quotient can be approximated to the nearest whole number as 2.
Answer:
(1)
Multiplying by 3 both sides of the equality you get that
3u is in the Span of the vectors 
.
(2)
That's not true, consider the following counter example.
is a linear combination of 
but is NOT a linear combination of 
Step-by-step explanation:
(1)
As the hint indicates, you know that
Then, if you multiply both sides of the equality by 3, you get that
And that's it. 3u is in the Span of the vectors
(2)
That's not true, consider the following counter example.
is a linear combination of but is NOT a linear combination of
Answer:
c. When a > 0 and b > 1, the function models exponential growth.
Step-by-step explanation:
You have exponential decay when a > 0 and 0 < b < 1.
