the point (-4, -7) must satisfy both equations.
-7=-4k-7
k=0

I'm not sure how to do that. could u please tell me?
The new area is 25/2.
Please show the line and the table

2/3 of his money is 8.
8 times 1/3 is 4
thank you
triples are (-7, -1, 5), (-5, -5, 43/5), (-1, -7, 5), (1, 7, 5), and (5, 5, 7/5)
it's ok thanks!
Nice work, but I think it's multiples of 4 instead of just 4. :))

x is AB
There's a formula, it's called the "tangent secant theorem" or something, I don't really remember. Anyways, in this case, the formula says that:
9^2=16x
So AB=81/16
Tell me if I'm wrong though, I might have remembered the formula incorrectly
Thank you so much
thank you i got it!! :)
x is the original price of the tickets.
So, the new price, after the increase of tickets is 1.05x. Since the price of a rail ticket increased by £2.30, we know that £2.30 is 5% of the initial ticket price.
So the original ticket price is 2.30/0.05=£46
6^3 = 216 Possible Outcomes
1 way for 3
3 ways for 4
6 for 5
10 for 6
15 for 7
21 for 8
25 for 9
27 for 10
27 for 11
25 for 12
21 for 13
15 for 14
10 for 15
6 for 16
3 for 17
1 for 18
Multiples of 4 = 4 , 8 , 12 , 16
So
( 3 + 21 + 25 + 6) / 216 =
55 / 216
There are three ways three dice can roll a 4. (possibilities are 1-1-2, 1-2-1, and 2-1-1)
There are 216 possibilities for a sum when you roll three die. So, the probabilitiy that you will roll a 4 is 3/216=1/72
We have this system
100 T + 94 PB = 776 (1)
85 T + 94 PB = 716 ⇒ -85 T - 94 PB = - 716 (2)
Add (1) and (2)
15 T = 60
T = 60 / 15 = $4 a box for truffles
And
100 (4) + 94 PB = 776
400 + 94 PB = 776
94 PB = 776 - 400
94 PB = 376
PB = 376 / 94 = $4 a box for peanut brittle
That's me
(10, 8) ( -15 , 18)
Slope = ( subtract y coordinates in some order) / ( subtract x coordinates in the same order ) =
So....
( 18 - 8 ) / ( -15 -10) =
10 / -25 =
-2 / 5
NP !!!!
thanks again, CPhill!
KF, you've posted 17 questions on this site and every single one of them has more than one question on it. I mean, just saying, this site isn't really for posting your homework and expecting people to do it for you. Just saying. Do the problems the best you can yourself first.
5% of 2.699 = .05 * 2.699 = .13495
2.699 - .13495 =
2.56405 g / cm^3
For the greatest observed density......add 2.699 + .13495
probably something like a TI-84

The scale factor = 1.10
The % increase = (1.10)^2 = 1.21 = 21% increase
