Find the coordinates of the fourth vertex that completes the construction of the rectangle on the coordinate plane.

A) (2, −4)

B) (4, −2)

C) (−2, 4)

D) (−4, 2)

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.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
