Use algebraic methods to prove that the given function has an x-intercept that is equal to its y-intercept. In your final answer
Llana [10]

Given the function, y = x/( x^2 – 1)

Add x and subtract x from (x^2 – 1) to make it a complete square

y = x/(x^2 + x – x – 1)

 y = x/[x(x + 1) – 1(x + 1)]

y = x/[(x – 1)(x + 1)]

 

 

In order to find the y -intercept, we set x = 0

When x = 0

y = 0/[(0 – 1)(0 + 1)]

y = 0.

Therefore, the y-intercept is zero.

 

In order to find the x -intercept, we set y = 0

When y = 0

0 = x/[(x – 1)(x + 1)]

The only way the product of a division will be zero is if the numerator is zero

So, if x/[(x – 1)(x + 1)] = 0

x = 0

Therefore, the x-intercept is also zero.

 

Since both x- intercept and y- intercept equal zero,

Then, the given function has an x-intercept that is equal to its y-intercept

Find x and round to the nearest tenth:)
Thepotemich [5.8K]

Answer:

x = 31.8°

Step-by-step explanation:

Applying the Law of Sines, we have:

\frac{sin(x)}{12} = \frac{sin(75)}{22}

Multiply both sides by 12

\frac{sin(x)}{12} \times 12 = \frac{sin(75)}{22} \times 12

sin(x) = \frac{sin(75) \times 12}{22}

sin(x) = 0.5269

x = sin^{-1}(0.5269)

x = 31.8° (nearest tenth)

5+2x6=5+12 can somebody help me with this problem?
marusya05 [52]
First, do 5 = 12 = 17.
Look at the numbers you have.
What numbers can make 17?
You basically add ().
You add the () between 2 x 6 (2x6) to show that you do that first.
Then, once you get the answer for that, add 5.
5+(2x6) = 17.

I hope this helps! :D
