Answer:
f(4) = 3
x = -1
Step-by-step explanation:
Line graphed shows a linear function.
Since this line passes through two points (4, 3) and (-1, 4)
Let the function is,
f(x) = mx + b
where 'm' = slope of the line
b = y-intercept of the line
Slope 'm' =
=
=
f(x) =
Since a point (4, 3) lies on the line,
f(4) =
3 =
b = 3 + 0.8
b = 3.8
Therefore, f(x) = -0.2x + 3.8
For x = 4
f(4) = -0.2(4) + 3.8
= -0.8 + 3.8
= 3.0
For f(x) = 4
4 = -0.2x + 3.8
0.2x = 3.8 - 4
x =
x = -1
Answer: Amount that they paid in 2007 is 1.01 millions.
Step-by-step explanation:
Since we have given that
Number of millions paid last month = $1.29 millions
According to question, it was 26% above what they paid in 2007.
Let the amount paid in 2007 be x
So, our equation becomes,
Hence, Amount that they paid in 2007 is 1.01 millions.
