We  can solve  these  two equations....

a(2) + 3  =  2 + 5             2(-2)  - b  =  -2 + 5

2a  + 3  =  7                        -4 - b  =  3

2a =  7 - 3                            -4 - 3  =  b

2a  =  4                                    b  = -7

a  = 2

a +  b  =  2 - 7  =  - 5

Thank you so much!

Inverse proportionality

x = (4*3.67)/1.835 = 8kPa

P.S: This the Boyle's Law

sin Z  =   sqrt ( 29^2  - 7^2) / 29  =   6sqrt ( 22) / 29

tan Y  =    7  / 6 sqrt (22)   =   7sqrt22) / 132

Y

6sqrt (22)        29

X              7                         Z

2(x - 8)^2  +  4       (expand)

2 (x^2  - 16x + 64)  +  4  =

2x^2  - 32x  +  128 + 4  =

2x^2  - 32x  +  132         a  =  2       b  = -32        c   =  132

So

3(2)x^2   + 3(-32)x + 3 (132)   =

3  ( 4x^2  - 32x  + 132)  =       (factor out 4)

3 * 4  ( x^2  - 8x + 33)   =

12   [ x^2  - 8x  +  16  +  17 ]   =         (factor x^2 - 8x + 16)

12 [ ( x - 4)^2  +  17 ]  =                     (distribute  the 12  across the terms in the brackets )

12 (x - 4)^2  +  204

h =  4

wait so the answer is 1/7? thats what i got.

okay weird the answer should be 1/7, because 25/175 is equal to 1/7 

;-; is it THAT hard i try to be nice but ....

This might be a better visual that made!

 |------------|

 |------------|

      2x

And no i did not understand a single thing

Your explanation sucks

It asked for a fraction and the weird thing is that no one can solve this to get 1/7

sorry I didnt explain it in too much detail I didnt have much time.

I hope you understand it.

If the perimeter of 3 rectangles is 90cm, the perimeter of 1 is 30.

If the width of the rectangle is x, than the whole rectangle would be 6 x.

30=6x, so x=5

the length of one rectangle is 10 

your welcome :)

Will say that John has 100 magnets. If John has 100 magnets, Liam will have 175. If Liam gave away twice as many magnets as John, and John has 25 magnets left, Liam gave away 150 magnets. Liam will end up with 25 magnets. And I think you can continue from there.

ye np tho when I was younger I used to watch that show called MAD which is why i recognized it so I'm guessing they took the Magazine and made it into a show i was like 5 or 7ish when it came out haven't seen it in like 10 yrs

y =  120  + 15x

can you screenshot the problem???

THX....Haven't seen that show.....it  actually originated from the old MAD magazine  (maybe now defunct  )

Inputs: -13, 20, 0, -4, 11, -1, 17, (blank space)

Outputs: -15, -11, -9, -2, -1, 5, 5, 13

We  have  the points

(-13, -15)   ( 20, -11)   ( 0, -9)  ( -4, -2)  ( 11, - 1)  (-1, 5)  ( 17, 5)  ( x, 13)

We cannot  have  the  same  x  going to two different y's

So

-5   is OK

-1  is not   ...we  would have  ( -1,5)  and (-1. 13)

0  is not......we would have  ( 0, - 9)  and (0, 13)

2 is OK

11 is not....we would have  ( 11,  -1)  and (11, 13)

17 is not....we would  have  (17,5)  and (17,13)

 I like your pfp its from M.A.D that old show on cartoon network im guessing

its wrong srry

No prob....

We  can  have a variable

Consider

( x^2  - 16) / (  x - 4)    =

[ ( x + 4) ( x - 4) ]  / ( x - 4)  =

x + 4
