P = price of tickets
8.50p = 42.50
you then divide 8.50 on both sides
8.50p = 42.50

8.50 8.50
p = 5
meaning Allison bought 5 tickets in total.
To see if (2,5) is a solution of the line y = 3x - 10, you need to plug in the coordinate values for x and y. This gets you 5 = 3(2) - 10. Evaluating the right side gives 5 ≠ -4, which is not a true statement. This means that the answer to your problem is no, (2,5) is not a solution of y = 3x - 10. Hope this helps and have a nice day!

Answer:
-3 is the value of k in g(x)=kf(x)
Step-by-step explanation:
Both functions cross nicely at x=-3 so I'm going to plug in -3 for x:
g(x)=kf(x)
g(-3)=kf(-3)
To solve this for k we will need to find the values for both g(-3) and f(-3).
g(-3) means we want the y that corresponds to x=-3 on the curve/line of g.
g(-3)=-3
f(-3) means we want the y that corresponds to x=-3 on the curve/line of f.
f(-3)=1
So our equation becomes:
g(-3)=kf(-3)
-3=k(1)
-3=k
So k=-3.
