This is the expression 18k + 22 p - 10
Answer: none of these are right, the correct answer would be 7
Step-by-step explanation:
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:
h = 5
Step-by-step explanation:
area = 1/2 base × hight
base = 3 +h
hight =9 + 6 = 15
60 = 1/2 × 15 × (3+h)
120/15 = 3 + h
8 = 3 + h
h = 5
