Answer:
The formula for this arithmetic sequence: 
Step-by-step explanation:
As
- weighing about a ton on their 14th birthday, weighing about a ton on their 14th birthday, the average T-Rex grew 4.6 pounds per day from the age 14 to 18 years.
Let the general term 
of the arithmetic sequence represent the weight in tons of the T-Rex where 
is the number of days.
Therefore, the formula for this arithmetic sequence:

Answer:
Step-by-step explanation:
reflection
Step-by-step explanation:
Sn=n/2(2a+(n-1)d)
910=n/2{2a+(n-1)d}
1820=n{2a+(n-1)d}
1820=20{2a+(20-1)d}
1820=20{2a+19d}
91=2a+19d
An=a+(n-1)d
95=a+(20-1)d
95=a+19d
91=2a+19d
---------------
4=-a
a=-4
91=2a+19d
91=2(-4)+19d
91=-8+19d
91+8=19d
99=19d
d=99/19
A=-4
Answer:
-2
(The coordinate point is (0,-2))
Step-by-step explanation:
First, make an equation of the line.
Start off with finding the slope:
Slope = (13-1)/(5-1) = 12/4 = 3
Then solve for the y-intercept though substitution and simplification:
y=mx+b --> 1=3(1)+b --> 1=3+b --> b= -2
So the answer is -2.
