X - 2y = - 9
7x + 2y = 1
x - 2y = - 9
(+)
7x + 2y = 1
___________
8x = - 8
x = - 1
- 1 - 2y = - 9
2y = 8
y = 4

<span>United States population is 10 times as big as Canada's population
which is
1/10*US =32 million
US= 32 million * 10 .
US=</span> 320 million
Given:
The function is
To find:
The tangent line to the graph of f(x)=x at point (0,0).
Solution:
We have,
It is a linear function because the highest power of the variable is 1.
We know that the tangent line to a linear function at any point is the line itself.
Derivative of given function is
So, slope of the tangent line is 1. It is given table the tangent line passes through the point (0,0). The equation of tangent line is
Therefore, the tangent line to the graph of f(x)=x at point (0,0) is y=x.
