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

2/3 of his money is 8.
8 times 1/3 is 4
triples are (-7, -1, 5), (-5, -5, 43/5), (-1, -7, 5), (1, 7, 5), and (5, 5, 7/5)
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
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
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
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.
probably something like a TI-84

f(x)+x^2= (x+1)(x-2)(x+3)(x-4)
f(1)=2*(-1)*4*(-3)-1^2=23
