.275 is 275/1000 in decimal form
Answer:
Step-by-step explanation:
Hello,
Basically, we need to prove that is irrational
Let s assume that is rational
it means that we can find p and q (q different from 0) two integers <u>with no common factors other than 1 </u>
so that
And then we can write that
So is even so it means that p is even
so is divisible by 2*2=4
as it means that is even, meaning q is even
wait, p and q are then even !? but by definition they have no common factors. This is not possible.
so our assumption that is rational is false
So it means that this is irrational
and then is irrational too
Hope this helps

<h3>The given system of equations
and</h3><h3>
has exactly one solution</h3>
Step-by-step explanation:
Given that the system of equations and
has exactly one solution
<h3>For :</h3><h3>Now to show that the given system of equations has exactly one solution :</h3><h3>Solving the given equations (1) and (2) to get solution</h3><h3>Adding the equations (1) and (2) we get</h3>
______________
<h3>Therefore the value of is y=-6</h3><h3>Substitute the value of y in equation (1) we have</h3>
Therefore the value of x is x=0
<h3>Therefore it has exactly one solution is (0,-6)</h3><h3>Therefore the given system of equations
and</h3><h3>
has exactly one solutione given system of equations has exactly one solution</h3>
