Answer:
7=-10s-3, would mean that s= -1
Step-by-step explanation:
From x equals five to nine, the y value changes as follows
+10,+2,+1,+3
Assuming that "average" implies the mean, the sum of all four values is 15. Then divide 15 by the four values added = 15/4 = 3 3/4 or 3.75
Answer:

Step-by-step explanation:
Given
See attachment for model
Required
Determine
from the model
The model is represented by:

To get:
, we consider the first partition
The number of shaded box is 63 ---- this represents the denominator
The total boxes shaded at the bottom is 36 ---- this represents the numerator
So, we have:

To get:
, we consider the first partition
The number of shaded box is 63 ---- this represents the denominator
The total boxes shaded at the bottom is 16 (do not count the gray boxes) ---- this represents the numerator
So, we have:

The equation becomes:
