Answer:
B
Step-by-step explanation:
Y=7-3x
Y=10 if x=-1
1-*7-3
=10
The polynomial function is shown about between 10 and 15.
Answer:
Step-by-step explanation:
Given that x and y are proportional and the equation relating them is
y = rx ← r is the constant of proportionality
To find r use any ordered pair from the table
Using x = 9, y = 4.5 , then
4.5 = 9r ( divide both sides by 9 )
= r , that is
r =
