You need to show us the spinner so we can see each section.
If y = x+2 and x = -3 then we can say that y = -3+2 after replacing the 'x' with -3
From here, we just add -3 and 2 to get -1 which is why y = -3+2 turns into y = -1
So together x = -3 and y = -1
They pair up to form (x,y) = (-3,-1)
Answer:
Options A and C are correct choices.

Answer: Variable - Ratio Schedule
Step-by-step explanation:
Schedules of reinforcements are guidelines which give insight as to what actions would be rewarded. They are used as teaching tools. There are basically two types of reinforcements and they are the Continuous and Partial reinforcements.
While the Continuous reinforcements are teaching methods which explain that a response is met with an equal outcome consistently, the Partial reinforcements are used after the lessons are established as in the case of continuous reinforcement. In Partial reinforcements, the response is met with an outcome inconsistently.
In variable - ratio schedules, there is a reinforcement of response after an unknown number of responses. In the lottery game above, no one knows ( unknown response), how many tickets a player has to buy before he is rewarded (outcome/reinforcement). So the outcome/reward is inconsistent and the response is unknown.
The cost function is a quadratic. The basic form of a quadratic equation is ax^2 + bx + c = 0. You must find the values of the coefficients a, b and c.
Use the given data to construct 3 simultaneous linear equations in x:
5 = a(2)^2 + b(2) + c
143 = a(4)^2 + b(4) + c
869 = a(10)^2 + b(10) + c
You must solve for a, b and c and then write the quadratic equation
y = ax^2 + bx + c that governs the production costs. Then let x=7 and calculate y, which is the figure you want.
Using matrices, I found that a=6.5, b=30 and c=-81.
Can you now write the quadratic equation and evaluate it at x = 7?
