Small circle 2/4 = 1/2 and the big circle is 3/5 i hope this is correct. im truly sorry if this was wrong

Answer: D) The data repeats every 4 minutes</h3>
Explanation:
The period of a function measures how long a cycle takes. Think of tides on a beach. There's a regular pattern that can be predicted whether its high tide or low tide. Time is often the critical component with the period. Since choice D mentions time and the key term "repeat", this is why it's the answer.
The other values, while useful elsewhere, aren't going to tell us anything about the period. The initial value being 5 doesn't tell us when y = 5 shows up again, and if the function is repeating itself at this point or not. So info about choice A is not sufficient to determine the period. The same goes for choices B and C as well.
1063 is the answer for ii) idk about b
I believe the answer would be true.
You can use the substitution method.
Let's choose the second equation in terms of y (which is much easier),
-y = 4 - x
y = -4 + x
y = x - 4
Substitute this to the first equation to get the value of x.
-5x + 3(x - 4) = 6
-5x + 3x - 12 = 6
-2x = 6 + 12
-2x = 18
x = -9
Substitute it to the first equation that we have used.
y = -9 - 4 = -13
