Answer: £450
Step-by-step explanation:
If they bought 2 tickets, they could get an extra ticket for free. As there are three of them, they would buy 2 tickets, get one for free and then buy another ticket to make it four.
In that case they would have only paid for 3 tickets.
The total cost of 3 tickets is:
= 600 * 3
= £1,800
The 4 of them would therefore have to pay:
= 1,800 / 4
= £450
Our function is:
f(x) = 2^x + 2
To find which graph represents this function we should find at least 2 points. We take some value of x we want and calculate y for it. And do that at least 2 times (can be done 1 time but its likely that some graph match in some points)
for x = 0 we get
f(x) = 3
for x = 1
f(x) = 4
we can also note that f(x) cannot be less than 2 because 2^x is always greater than 0, and that as x increments f(x) increments. With all of this in mind answer is last graph.
Answer is graph D
The correct answer is (D) because 3 multiple 1/3, the 3 go with 3 and we get the 1. And 9 multiple 1/3, the 9 go with 3 and we will go 3 multiple 1 and we will get 3.
We know that
for
y=a(x-h)^2+k
vertex is (h,k)
given vertex is (3,5)
y=a(x-3)^2+5
we are also given
(5,-3)
x=5 and y=-3 is a possible solution
-3=a(5-3)^2+5
-3=a(2)^2+5
minus 5 both sides
-8=a(4)
-8=4a
divide by 4 both sides
-2=a
the equation is
