If x = 2 and y = 7, then 7 = 3f(4) + 1, so so f(4) = 2.  The point on the graph is (2,2), and the sum is 4.

1)  If you had 6 different letters, the answer would be 6!.

     Since you have multiples, you need to divide by the factorials of the multiples:  Answer = 6! / (2! x 3!)

     -- because you have 2 Bs and 3 Cs.

2)  You can find the value of each one individually, and sum them together.

      Or, since this sum gives you half of the entries of the 13^th row of Pascal's triangle, you can find the sum of that row

      (which is 2¹³) and divide that  answer by 2.

3)  Since the first digit can be any digit but zero, you have 9 choices for the first digit.

     Since the next digit can be any digit that doesn't match the first digit, you again have 9 choices for the second digit.

     Similar, for digits 3 and 4.

     Total:  9 x 9 x 9 x 9

i got 1208

It says 2 white balls, or a red ball. Not both.

there are 7x cards

7x = 84

x = 12

4 times 12 = 48

48 cards

THANKS!!

Well, it's quite possible I read the question incorrectly (I assume you refer to part 2). It's also possible my logic is wrong. However, it would be nice to know in what way I read it incorrectly. I certainly misread it at first as I initially assumed part 2 required at least two white balls and the red ball. I then noticed the question specified at least two white balls or the red ball. Perhaps you can explain which bit I read incorrectly (or else supply the correct answer so I might be able to work out the error myself).

I'm sorry Alan, that wasn't the correct answer. I don't think you read the question right, but thank you for trying!

p + c = 16

275p + 325c = 4950

275 p + 325 c = 4950

275 p + 275 c = 4400

50c = 550

c = 11

11 pounds

Not anymore xD

what I don't think is right is that all the animals are distinct.

I suspect the problem want's them identical by type.

Ooops sorry....I didn't read the answer

( - inf  ,  -4.6 )      parentheses on both sides      not brackets....

I got that but it was wrong...

There ISN'T much of a difference...that is why it is a 'slight' correction ! 

i dont see much a differance (srry for my spelling)

slight correction   ( - inf , -4.6 )          (edited)

each long side (there are 2)  will be     48 x 20 feet      two of them    is    2 x 48 x 20   feet

   each long side    is 2 x 62 feet                                   two fo them    is    2 x 2 x 62     feet

Add the red expressions.......

the link kind of dosn't work, tried to open it but only showed black, i waited but nothing so i cant help you srry but 50 degrees may be right

-4(x + 4) > x + 7.

 -4x - 16 > x + 7   | -x + 16

        -5x > 23       | : (-5)

           x < -4.6

[-inf , -4.6]

ok thx im gonna try anwser those now

but as stupid as this sounds, what does 'in terms of x' mean i compleatly forgot and i cant remember what that means but quick question, is x=60

and by the power invested in me, someone may butt in to anwser this 'but as stupid as this sounds, what does 'in terms of x' mean i compleatly forgot and i cant remember what that means'

Are your last two equations one problem?

If so:

3^p  =  9·(27)^q     --->     3^p  =  3²·(3³)^q      --->     3^p  =  3²·(3^3q)     --->      3^p  =  3^{3q + 2}     --->     p  =  3q + 2​

log₂7 - log₂(11q - 2p)  =  1     --->     log₂[ 7 / (11q - 2p) ]  =  1     --->     ​7 / (11q - 2p)  =  2¹ 

                                                                                                     --->     7  =  2( 11q - 2p )      --->     7  =  22q - 4p

Since  p  =  3q + 2     --->     7  =  22q - 4(3q + 2)

                                  --->     7  =  22q - 12q - 8

                                  --->     7  =  10q - 8

                                  --->     15  =  10q      --->     q  = 1.5

Substituting:  p  =  6.5

1/4 of the pool per 4 hours  hour is    1/4 * 1760 l/ 4hr = 110 l/hr

110 + 330 = 440 L/HR

1760 L  /  440 L/HR = 4 hours
