His score is 50
How to:
First test grade:0
Second test grade:50
Third test grade: 100
Add all three and divide by 3
The rule to represent the aritmathic sequence would be :
A(n) = 130 + (n-1) 13
the height in 13 days would be :
A(n) = 130 + (14-1) 13
A(n) = 130 + 169
= 299 inches
Answer: OPTION B
Step-by-step explanation:
The equation of a line that passes through the origin is the following:

Where "m" is the slope of the line.
By definition, Proportional relationships have the following form:

Where "k" is the Constant of proportionality.
Then, as you can notice, if you graph a Proportional relationship you will get a line that passes through the origin.
Therefore, based on the explained above, you can conclude that the option that shows a function that represents a Proportional relationship is the Option B.
Then, this is:

<span>8-4x<2x-10 add 4x both sides 8<6x-10 add 10 18<6x divide by 6 3<x x>3</span>
