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:
<em>Yes</em>
Step-by-step explanation:
g(x) = -
x +
y = -
x +
....... <em>(1)</em>
<em>(1)</em> × 4
4y = - x + 1
x = - 4y + 1
y = - 4x + 1
f(x) = - 4x + 1
∴ f(x) and g(x) <em>are inverses</em>
Answer:
x√5 = x square root 5
Step-by-step explanation:
√35x^5 ÷ √7x^3 = √(35x^5 / 7x^3)
√(35x^5 / 7x^3) = √(5x^5 / x^3)
√(5x^5 / x^3) = √5x^(5-3) = √5x²
√5x² = x√5
Answer: B
Step-by-step explanation:
A proper fraction is when a fraction has the numeration less than the denominator
