Step-by-step explanation:
Given function
We need to find 
value corresponding to each 
value.
So, plug each value in equation we get,
Now in next part of question it ask us to check each ordered pair.
Let us plug each value and value in the function 
we can see ordered pair 
true for function
Let the price of a notebook = X.
Multiply the cost of a notebook by the quantity, so you get 3x.
Add that to the price of a calculator to get the total spent:
60.54 = 45.87 + 3x
Now solve for x:
Subtract the cost of the calculator from both sides:
3x = 14.67
Divide both sides by 3:
x = 14.67 / 3
x = 4.89
A notebook cost $4.89

Answer:
Interest will amount to $142.58
Total amount Levi will have to pay back at the end of 6 months=$7271.58
Step-by-step explanation:
Simple interest=principal×rate×time
Principal=$7129
Rate=4%=0.04
Time=6 month=0.5 year
Simple interest=principal×rate×time
=$7129×0.04×0.5
=$142.58
Interest will amount to $142.58
Total amount Levi will have to pay back at the end of 6 months
=principal + total interest
=$7129+$142.58
=$7271.58
Standard quadratic equation .. y = a x^2 + b x + c
<span>parabola 'a' not equal to zero </span>
<span>a<0 parabola opens downward </span>
<span>a>0 parabola opens upward </span>
<span>when |a| >>0 the parabola is narrower </span>
<span>when |a| is close to zero , the parabola is flatter </span>
<span>when the constant is varied it only effects the vertical position of the parabola , the shape remains the same</span>
