Part A:
at the time x=4, the elevation = 3
at the time x=8, the elevation = 6
and 6-3=3in.
PART A ANSWER= 3in.
Part B:
the time period will be when the slope (y=mx+b) is the steepest. this would be from t=14 to t=18.
so, y=7.5-3= 4.5
ANS=4.5
an expression that determine the total cost of gym membership for any number of months is 10+19.99(x)
Given that:
cost per month = $19.99
Starting fee = $10
Months = x
So the expression for 1 person will be:
10+ 19.99(x)
thus an expression that determine the total cost of gym membership for any number of months is 10+19.99(x)

Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 9, - 10) and (x₂, y₂ ) = (- 2, - 5)
m =
=
→ C

Answer
Find out the how many people adopted a manatee this year .
To prove
As given
last year 40 people adopted a mantee through Fia's foundation.
This year 15% more people adopted a manatee
15 % is written inthe decimal form

=0.15
15% of the last year 40 people adopted a mantee = 0.15 × 40
= 6
Total number of people adopted a manatee this year = 6 + 40
= 46
Therefore the people adopted a manatee this year be 46 .
Hence proved
