AMSWER
C y=3x
EXPLANATION
The given ordered pairs are
(1,3) (2,6) (3,9) (4,12) and (5,15)
There is a constant difference in the y-values.
d=15-12=3
Let the rule that represent the function be
y=dx +c
When we substitute
d=3, we get;

We put x=1 and y=3 to obtain,


The rule is

Answer: 14.72
Step-by-step explanation:
Equation: 28x+20=1000
subtract 20 from both sides and your left with 28x=980
