Answer:
It is not direct variation
Step-by-step explanation:
y/7 = 2/x
y = 7×2/x
y = 14/x
And
y = k/x
k = 14 which is the constant of proportionality
: y ∞ 1/x
This is inverse variation
The correct answer for the question that is being presented above is this one: "<span>A) The temperature only adds 14 to the damage index." </span>Sven investigates the amount of damage to the head gaskets on the trucks in his fleet and find that the damage index depends on the ambient temperature.
These two quantities obviously refer to a picture or drawing that shows how they're related to each other. Without the picture, they're not related, and there's no answer.
2b + 5j = 6.35.....multiply by -2
4b + 12j = 13.20
----------------------
-4b - 10j = - 12.70 (result of multiplying by -2)
4b + 12j = 13.20
----------------------add
2j = 0.50
j = 0.50/2
j = 0.25 <==== jars
2b + 5j = 6.35
2b + 5(0.25) = 6.35
2b + 1.25 = 6.35
2b = 6.35 - 1.25
2b = 5.10
b = 5.10/2
b = 2.55 <=== brushes
so 1 brush (b) = 2.55 and 1 jar (j) = 0.25...total, if needed, = 2.80
