We have to divide 9.1 by 3576:
9.1 : 3576 = 0.0025447427
And rounded to the nearest whole number:
0.0025447427 ≈ 0
Answer:
Part 1) The rate of change is
Part 2) The initial value is 68
Part 3) The function rule to the linear model is 
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
step 1
Find the slope
take two points from the table
(0,68) and (15,85)
The formula to calculate the slope between two points is equal to
substitute the values
In a linear function , the slope is the same that the rate of change
therefore
The rate of change is
step 2
Find the y-intercept
we know that
The y-intercept is the value of y when the value of x is equal to zero
Looking at the table
For x=0, y=68
therefore
The y-intercept is
The y-intercept is also called the initial value
therefore
The initial value is 68
step 3
Determine the function rule to the linear model

we have
substitute

Answer: one
Step-by-step explanation:
it is 7
Answer:
36
Step-by-step explanation:
6 x 2= 12
12 x 3= 36
A's area is 4x3=12, B=2x3=6, so yes, A is twice the area of B
a Answer: YES
b Answer: One side doubled, the other stayed the same, so area doubled.
