What is the equation of the line that is perpendicular to the given line and psses through the point (5,3)?

 y= -1/a*x+5/a+3

Step-by-step explanation:

The equation of given line isn't known. Let it be y=ax+b (1)

So the equation of required line is y=-1/a*x+c                     (2)

Lets put 5 instead x and 3 instead y in (2) and find c

-1/a*5+c=3

c=3+5/a

The required equation is y= -1/a*x+5/a+3

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70
