Perpendicular lines have slopes that are negative reciprocals of each other, so the equation of the line in point-slope form is:

y-4=-\frac{5}{2}(x+3)

Rewriting this in standard form,

2y-8=-5(x+3) \\ \\ 2y-8=-5x-15 \\ \\ \boxed{5x+2y=-7}

So the equation 12 y equals 132 the equation 12 y equals 132
OlgaM077 [116]
12y = 132

Now, solve for y.

Do the inverse operation.

12y = 132
12y/12 = 132/12
y= 132/12
y= 11

Equation: 12y = 132
Y equals: 11

Please Help!!!! Please!!! A candlemaker prices one set of scented candles at $10 and sells an average of 200 sets each week. He
inna [77]

Answer:

y=-50x^2+300x+2000.

Step-by-step explanation:

It is given that a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week.  

Revenue=10\times 200=2000

If he reduces the price by $1,then he sells 50 more candle sets each week.

Revenue=(10-1)\times (200+50)=9\times 250=2250

If he reduces the price by x $1,then he sells 50x more candle sets each week.

R(x)=(10-x)\times (200+50x)

R(x)=10(200+50x)-x(200+50x)

R(x)=2000+500x-200x-50x^2

R(x)=-50x^2+300x+2000

It can be written as

y=-50x^2+300x+2000

Therefore, the situation can be modeled by the equation y=-50x^2+300x+2000.
