The answer I think maybe 8/3 this answer is a fraction of you are looking for one
Answer:
Step-by-step explanation:
I find it easier to work with the given standard-form equation. The parallel line will have the same x- and y-coefficients and a new constant. That constant can be found by substituting the given x- and y-values into the left-side expression:
x + 2y = 8 + 2·3 = 14
The parallel line is x + 2y = 14.

The perpendicular line will have the x- and y-coefficients swapped and one of them negated. (In standard form, the x-coefficient is positive, so in this case it is convenient to negate the y-coefficient.) Then the perpendicular line through (8, 3) is ...
2x -y = 2·8 -3 = 13
The perpendicular line is 2x - y = 13.
This problem looks really scary am I right? Well, actually it isn't too bad.
Let me explain something really quick.
When two like terms are over each other they equal 1. For instance 3/3. In the case of two numbers with powers they can also cancel out if they are the same number to a power. Here is why:
3² / 3² = (3*3) / (3*3) = 9/9 = 1
What if the powers are unequal?
3²/3 = (3*3) / 3 = 9 / 3 = 3
In the case where the powers are unequal (in the case of the example we have a power of 2 and a power of 1) we simply SUBTRACT the powers. In the case where the bottom is bigger you'll have the following problem:
3²/3³ = (3*3) / (3*3*3) = 9 / 27 = 1/3
If you have trouble understanding the subtraction simply write out the multiplication. Then if you see numbers which are equal on the top on the bottom cross them out till there are no equal terms on the top or bottom. In the case above you can cross out the 2 threes at the top and are left with 1 three at the bottom.
For our problem: (Note the ^ symbol is the same as saying being brought to the power of... so it's equivalent to the problem you see on your screen!)
5^4 / 5^6 = (5*5*5*5) / (5*5*5*5*5*5) = 1 / (5*5) = 1 / 25
Our answer is:
1/25
Answer:
that is the solution to the 2nd question
