Answer:
me bc im bored
Step-by-step explanation:
7. Easiest method is substitution. Since y=x/2, then:
2x+3(x/2)=28
8.Substituting again, we get:
3x-6x=6
-3x=6
x=-2
(-2,6)

By the consideration of <em>direct</em> proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.
<h3>How to find a constant of proportionality in direct proportional equation</h3>
Let x and y the number of weeks and the height of the plant, respectively. Given the consideration of <em>direct</em> proportionality, the height of the plant inasmuch as the number of weeks increases. Then, the constant of proportionality (in inches per week) is found by dividing the height of the plant by the number of the respective week:
k = 18 inches /6 weeks = 15 inches /5 weeks = 12 inches/4 weeks = 3 inches/week
By the consideration of <em>direct</em> proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.
