Answer:

Answer: y=3/2x+1

To find a line that is perpendicular, invert the slope and multiply by -1

so the original slope is -2/3,

invert it to get -3/2 then multiply by -1 to get 3/2

Put the given point (-2,-2) and the new slope into point intercept form: y+2=3/2(x+2)

Rewrite in standard form to get y=3/2x+1

Answer: 540

Step-by-step explanation:

Given : The owner of a stereo store wants to advertise that he has many different sound systems in stock.

Number of different CD players =6

Number of different receivers= 10

Number of different speakers = 9

We are assuming that a sound system consists of one of each .

Then by Fundamental principle of counting , we have

The number of different sound systems can he advertise = (Number of different CD players)x (Number of different receivers) x(Number of different speakers)

= 6 x10 x 9 =540

Hence, the number of different sound systems can he advertise =540
