How do you simplify this equation?
faust18 [17]

<u>Answer:</u>

The answer is B --> \frac{x^{2} }{3x^{2} -1}

<u>How I got that:</u>

<u />

These are really easy, you're simply looking for numbers that you can factor down. Like here:

I took:

\frac{4x^{2} }{12x^{2} -4}

and saw that I could factor out 4 from the denominator:

\frac{4x^{2} }{4(3x^{2} -1)}

and then I canceled out the common factor (4 because its on both sides):

\frac{x^{2} }{3x^{2} -1}

And there ya go!

Flight time from Houston to Orlando is 2 hours to 20 minutes. I arrived at Orlando at 4:15 pm. What time did I set of ?
Ede4ka [16]

Answer:

1:55 pm

Step-by-step explanation:

So, you arrive at 4: 15 pm in Orlando after a 2 hr and 20 minute flight from Houston.  So, lets start with the easy part: let's subtract the 2 hrs part.  

2 hrs earlier from 4:15 pm is 2:15 pm.

Then, you have to subtract the 20 minutes.  Well, it's quite obvious that if you left at 2:00 pm, that would be a total of 2 hrs and 15 minutes.  Just subtract the 15 minutes from the 2:15 pm.  However, it's 20 minutes, not 15, so you have to still subtract that last five minutes.  

So, 2:00 pm minus 5 minutes would equal 1:55 pm.

Use the elimination method to solve the system of equations. Choose the
hichkok12 [17]

Answer:

the ordered pair is (2,-1)

Step-by-step explanation:

We need to solve the system of equations using elimination method

12x - y = 25     eq(1)

9x + y = 17      eq(2)

Adding eq(1) and eq(2)

12x - y = 25

9x + y = 17

___________

21x = 42

x = 42/21

x= 2

Now, putting value of x in equation 1

12x - y = 25

12(2) -y = 25

24 -y = 25

Adding -24 on both sides

24 -y-24 = 25-24

-y = 25-24

-y = 1

Multiply both sides by -1

y = -1

the value of x = 2 and y = -1

So, the ordered pair is (2,-1)
