What is the slope of a line that is perpendicular to the line whose equation is 2y = 3x - 1?

The slope of the line is

Step-by-step explanation:

For any line , a line that is perpendicular to it is .

Therefore the slope of the perpendicular line is .

For our case therefore the slope of the prependicular is the reciprocal of multiplied by

-2/3

Step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
