Answer:

(5√11)/11 (option 1)

Step-by-step explanation:

If you multiply both the top and bottom by √11, you will get 5√11/11.

Next, make sure that the other answers are wrong.

5=√25, so

√11*5=√11*√25

So option 2 and 3 are incorrect.

#4 is obviously wrong, as you cannot simply switch the square root symbol between the denominator and numerator.

How would I graph this 8x-5y=15?

FromTheMoon [43]

This is linear. 8x-5y=15
-5y=15-8x
Divide -5
Y=8/5x-3.
Start at -3 on y axis and go down 8 points and right 3.

OMG PLS HELP WITH THIS IM PANICKING OMG I GOT A F IN MATH MY MOM JUST YELLED AT ME IM CRYING PLS HELP WITH THS- PLSS TELL ME WHA

Savatey [412]

Answer:

Ok, here we can see that Mr. Jones has $3,553 in his account, and he actually needs $18,469 to buy the car.

One way of representing this is:

Get a ruler, and draw a line that measures 3.553 cm (or close to it, it shouldn't be exact)

Now draw a line that measures 18.469 cm (again, this shouldn't be exact)

The difference between these lines represents the amount of money that Mr. Jones needs to save.

Now, how we find exactly the quantity?

Let's take the total cost of the car:

$18,469

Now let's subtract the amount of money that Mr. Jones already has:

$18,469 - $3,553 = $14,916

This is the amount of money that Mr. Jones needs to save if he wants to buy the car.

6x^2+bx+6=(3x+m)(nx+3) for all values of x what is the value of b?

ss7ja [257]

First, Delete these brackets on the right side:
$6x^{2}+bx+6=(3x+m)(nx+3) \\ 6x^{2}+bx+6=3nx^{2}+9x+nmx+3m \\ 6x^{2}+bx+6=3nx^{2}+(9+nm)x+3m$
Left side and right side are equal, so each parameters have to be equal. Next to "x^2" you've got parameters "6" and "3n". So:
3n=6 /:3
n=3

Free terms are "6" and "3m", so:
3m=6 /:3
m=2

Next to "x" you've got "b" and "9+nm" . We know, that m=2 and n=3 so:
b= 9+nm
b=9+2*3=9+6
So b=15
