Answer:
Option C is the answer.
Step-by-step explanation:
To find the equation of the straight line equation i.e, we must be given with the two points 
and 
Since from the graph the two points closest to the line are
and 
Equation of line with two points closest to the line :
where m is the slope.
First we find the slope(m)=
on simplify we get, 
.
Now, to find the equation of the line:
Apply distributive property on right hand side, we get
Adding both sides by 36, we get
.
The equation for the linear model in the scatter plot obtained by the two closest point 
closest to the line is,
Answer:
19.25
Step-by-step explanation:
Answer:
A statement asserting the equality of two expressions, usually written as a linear array of symbols that are separated into left and right sides and joined by an equal sign.

7x²=9+x
so
for
0=ax²+bx+c
so
7x²=9+x
mins 9 from both sides and minus x
7x²-1x-9=0
a=7
b=-1
c=-9
so the 4th one
Using an exponential function, it is found that the number 131.5 represents the initial value of the plane, in thousands of dollars.
<h3>Exponential function:</h3>
A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the function for the value of the airplane after t years is given by:
Hence A(0) = 131.5, which means that the number 131.5 represents the initial value of the plane, in thousands of dollars.
