Given a slope m, the slope m' of a line perpendicular to m is the opposite of the inverse of m

In other words:

mm' = -1 \iff m' = -\dfrac{1}{m}

So, the slope of CD is -5/2.

Let's find the unit rate stemming from $18 for 4 games:

$18

-------------  =  $4.50/game

4 games

Let's do the same for $27 for 6 games:

$27

------- = $4.50/game (same as before)

 6 g

Thus, the const. of prop. is $4.50/game, and the cost function is

C(x) = ($4.50/game)x, where x is the # of games played.

-2x+3y=-13 and 3x-3y=12
Tresset [83]

Answer:

x = -1 ,y = -5

Step-by-step explanation:

--> -2x + 3y +3x-3y = 12-13

--> x= -1

then

--> -2(-1) +3y =-13

--> 2+3y= -13

--> 3y = -15

--> y =-15/3

--> y = -5
