2x^2 + 3xy – 4y^2 when x = 2 and y = - 4  .....  "plugging in,"  we have  ......

2(2)^2 + 3(2)(-4) - 4(-4)^2  =

2*4  + (6)(-4) - 4(16) =

8 - 24  -  64   =

-16 - 64   =

-80

Time = D/R   ....so we have

Time = 1.2miles / [3miles/hr]  = [1.2/3] hrs. = [12/30]hrs = [24/60]hrs = 24 minutes

The answer is four

The side of the square mirror = √256 = 16 in

The area of the rectangular mirror will be  (16)(16 + 2)  = (16)(18) = 288 sq. in.

No. of People            Cost

1                             9.50

2                            19.00

3                            28.50

4                            38.00         

          etc.

If we divide the cost in each row by the number of people in that row, we always have the proportion (ratio) of 9.50 / 1

Note, Anonymous.....

m = -3n + 7    is the same thing as   m = 7 - 3n    ......

M=-3N+7

If i am correct, CPhill has forgotten the negative 3.

1/3(x-2)=3  multiply both sides by 3  to clear the fraction

(3)(1/3)(x - 2) = (3)*3

x - 2 = 9    add 2 to both sides

x = 11

6.7 x 70 = 469 miles

This means that we want the thing we are "solving for" on one side of the equation and everything else on the other....so we have

m+3n = 7       subtract 3n from both sides

m = 7 - 3n

And that's it !!!

-6+12<-22 

6 < -22  

This is false

cot Θ = x/y = 4/7

tan Θ = y/x = 7/4

For the rest of the identities we need to find "r"....this is given by  √[x^2 + y^2]  =  √[4^2 + 7^2]  = √65

So

sin Θ  = y/r = 7/ √65    

cosec Θ  is the reciprocal of the sine = √65/7

cos Θ = x / r  = 4/ √65

sec Θ is the reciprocal of the cos = √65/4

Message me back I have one thing to ask you

Pi is an irrational number that does not "terminate".....and any multiple of an irrational doesn't terminate, either........thus, 28pi  is non-terminating

[30 - 4*2 ] / [ 2 * 2 ]^2   =   [30 - 8] / [4]^2  = [22] / [16]  = 11 / 8

Yep! I can't, you got me there! But is it not Amber (girl) or Tom (boy)?

√77/√7  =  √(7 * 11) / √7 =  [√7 * √11] / √7   =  [√7/√7] * √11  = 1 * √11  = √11

No prob

i dont know but you can look whats the degrees of florida or wherever and copy the little circle and paste or you can speel out degress as the answer

1 inch = approx 2.54 cm

22 minutes x 52 = 1144 minutes

And the number of minutes in a week =  7 x 60 x 24 = 10080

So....the number of weeks it will take to watch =  1144/10080  =  about .113  or about  11.3%  of a week

Is it that bad?

I agree with the anon. It’s god-awful! My cat clawing a keyboard can produce something more coherent than this. Want an example of technology destroying us. This website hosts your post of incoherent drivel. The computer and net connection you use, allows you to post this noxious slop of careless indifference; that, and the related bad attitude, potentially affects the psyche of hundreds of young readers.
