Solve: x/x+2 + 5/x-3 = 25/x2-x-6

Paraphin [41]

Answer:

x1=3 x2=-5

BUT x1=3 is not an answer because it doesnt respects the range on the original ecuation, so x2=-5 is the solution

What multiplies to 16 and adds to 18?

KonstantinChe [14]

The number 8 is a multiple of 16, 2 x 8 = 16 . And the number 8 + 10 = 18

So, I would think it's 8.

Hope I was able to help you. :-)

15, Evaluate 6 choose 4.

Novosadov [1.4K]

Answer: The required result is 15.

Step-by-step explanation: We are given to evaluate the following :

"6 choose 4".

Since we are to choose 4 from 6, so we have to use the combination of 6 different things chosen 4 at a time.

We know that

the formula for the combination of n different things chosen r at a time is given by

$^nC_r=\dfrac{n!}{r!(n-r)!}.$

For the given situation, n = 6 and r = 4.

Therefore, we get

$^6C_4=\dfrac{6!}{4!(6-4)!}=\dfrac{6!}{4!2!}=\dfrac{6\times5\times4!}{4!\times2\times1}=15.$

Thus, the required result is 15.

Please help! Thank you if you do :)

Kruka [31]

Step-by-step explanation:

A(-5,1) and B(0,4)

$m \: = \: \frac{y2 - y1}{x2 - x1}$

X1=0 , Y1=4 X2= -5 , Y2=1

$m \: = \: \frac{3 }{5}$

$y - y1 = m(x - x1)$

y - 4 = ⅗(x-0) ==> y - 4 = ⅗ X ==> y = ⅗ X + 4

<u>C</u> is the answer
