Step-by-step explanation:
To find : Match each number in scientific notation with the number written in standard form and in a step by step process.
Solution :
From scientific to standard we expand the power of 10.
1)
Remove decimal and open the power,
Therefore,
Match with Option 3.
2)
Remove decimal and open the power,
Therefore,
Match with Option 1.
3)
Remove decimal and open the power,
Therefore,
Match with Option 2.
Answer:
The equation of the line is 2 x - y + 5 = 0.
Step-by-step explanation:
Here the given points are A( 1, 7) & B( -3, - 1) -
Equation of a line whose points are given such that
( ) & (
)-
y - =
( x -
)
i.e. <em> y - 7= ( x- 1)</em>
<em> y - 7 = ( x -1)</em>
<em> y - 7 = 2 ( x - 1) </em>
<em> y - 7 = 2 x - 2</em>
<em> 2 x - y + 5 = 0</em>
Hence the equation of the required line whose passes trough the points ( 1, 7) & ( -3, -1) is 2 x - y + 5 = 0.
