Select ALL the statements that have exactly ONE solution (a. Only one value will make the equation true
(b. The solution is true always. An identity is always true, for any value of x
(c. No values will make the equation true.
(d. The solution is never true. A contradiction is never true for any value of x
(e. The solution is true sometimes. A conditional equation is true for some value of x.
(f. Any value will make the equation true
(g. The lines will be in top of each other
(h. The lines will be parallel (never touch).
(I. The lines will cross each other at one po

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

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

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
