y=-(2/5)x-4       multiply everything by 5

5y = - 2x - 20    add 2x to both sides

2x + 5y = -20

And that's in S.F.

Yep you got it right I believe!

Hey I  1-1/4 equals 3/4! 

was he riding a horse by any chance?! XD or is the trains name Monday?

Okay thanks CPhill!!!! 

Can you please ask the question in English I can tell that the last word is Fractions! I speak a little French but I cannot tell what the first two words are?!

Yep.....that's it.....(as long as the number isn't 0 )

Let Luka's score be x

Then Tony's score  =  x + 12

And Jack's score = x / 3

And  Jack's score was 1/9th of Tony's....so...

Nine times Jack's score = Tony's  .....so....

9(x/3) =  x + 12     simplify

3x = x + 12     subtract x from both sides

2x = 12     divide both sides by 2

x = 6

And Tony's score is x + 12 = 6 + 12  = 18

75*3=225

60+80=140

225-140=85

85

Slope = change in y / change in x

So from the first point to the second, y changes by -3

And x changes by -3

So -3 / -3   = 1

And that's the slope

So we have

Area =(1/2)(Base)(Height)

A = (1/2)(8)(A - 6)

A = 4(A - 6)

A = 4a - 24    subtract 4a from both sides

-3A = -24      divide both sides by -3

A  = 8 sq. units

I know this

Area=Base*Height/2

The rest?  Not sure.....

A bunch of other numbers. 

Maybe Freddy left late night and came back early morning?  Or it isn't counting the train time

Jake be the name

Pretty sure inverse functions are used for the oppsoite of what the length is, so, quite possibly?

Good job!!!!

(12+34i) and (12−34i) divided by (2−3i)

(12 + 34i)(12 - 34i) =

144 - 1156i^2 =

144 - 1156(-1) =

144 + 1156 =

1300

And

1300 / (2-3i)    multiply top and bottom by the conjugate of 2 - 3i

1300(2 + 3i) / [ (2 - 3i)(2 + 3i) =

1300(2 + 3i) / ( 4 - 9i^2)

1300(2 + 3i) / 13 =

2600/13 + 3900i / 13 =

200 + 300i

Why thank you....you said the name is Jake?

WOW HAPPY!  You are great!  (and CPhill!)

Thanks, h7......!!!

That would be me.....oops!  I subtracted 24 from the total.  CPhill is correct....I'll edit??

One is wrong........thanks anyways!

99*54/12+96-(75-61)

Multiply 99*54 = 5346

5346/12 = 445.5

445.5 + 96 = 541.5

So

541.5 - (75 - 61)  =

541.5 - (14) =

527.5

10,701 to nearest thousand=11000

6683 to nearest thousand=7000

11000+7000=18000
