To make an line perpendicular to another, you must take the slope of the first line and find its negative inverse to put in the second.
3y=x-6 --> y=(x-6)/3 --> y=1/3x-2
The slope of the first line is 1/3 so the slope of the second line will be -3.
Now you must use the point slope formula to find the actual equation of the second line.
y-y1=m(x-x1) --> y-(-7)=-3(x-4) --> y+7=-3x+12 --> y=-3x+5
Now you need to translate that to function notation, which is pretty easy. Simply remember f(x) = y. So...
f(x)=-3x+5, and that's your answer.
Remember to check your answers using a graphing calculator. If you don't have one, you can use one online. I recommend using https://www.desmos.com/calculator.

DanielleElmas [232]

Answer:

6.48 dollars total,

Step-by-step explanation:

First, you would want to multiply the amount of money per pound, by the amount of pounds. 1.60 multiplied by 4 1/2 or 4.5, would equal to 7.2 dollars. In order to find 10% of 7.2, your would need to multiply 7.2 by 0.10, which would give you 0.72. Then you would subtract 7.2 by 0.72 to get 6.48. So your answer would be 6.48 dollars. Hoped this helped.

Neko [114]
Let x = software program
Let y = video game

x < 200 ; y < 300

x + y < 425

50x ; 35y

x = 200 ; y = 225
50(200) + 35(225) = 10,000 + 7,875 = 17,875

x = 125 ; y = 300
50(125) + 35(300) = 6,250 + 10,500 = 16,750

x = 175 ; y = 250
50(175)  + 35(250) = 8,750 + 8,750 = 17,500

It is more profitable to maximize production of software program when working within the limits provided.
