Answer:
7.94
Step-by-step explanation:
An equation is formed of two equal expressions. The value of the constant of proportionality is 0.41.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given there exists a proportional relationship between the number of juice bottles bought, j, and the total cost in dollars and cents. Therefore,
c ∝ j
c = kj
As the relation is represented by the equation c=0.41j. Therefore, the value of the constant of proportionality is 0.41.

Step-by-step explanation:
awesome please check out my newest question I need help!!!!!!!
Answer:
use the formula A = 1/2ab(sin C)
Step-by-step explanation:
To find the slope of a line, use this formula:
m = (y2-y1)/(x2-x1) where m is the slope, and (x1, y1) and (x2, y2) are points.
If I plug points P and Q into the slope formula, we get:
(1-5)/(-2+8) = -4/6 = -2/3
The slope is -2/3
