Answer:
The expression that represents the length of 1 of the triangle's legs is y + 5
Step-by-step explanation:
An isosceles triangle has two sides equal which are the triangle legs. Let b represent the base of the triangle and l represent one of the triangle's legs. Then, the perimeter, P is given by
P = l + l + b
i.e P = 2l + b
From the question, P = 6y + 12 and b = 4y +2
∴ 6y + 12 = 2l + 4y + 2
6y - 4y + 12 - 2 = 2l
2y + 10 = 2l
∴ 2l = 2y + 10
Then,
l = (2y+10)/2
l = y + 5
Hence, the expression that represents the length of 1 of the triangle's legs is y + 5

Answer:
First table
Step-by-step explanation:
We have to find the set of value which could be from a direct proportion.
We know that
Direct proportion :
When x is directly proportional to y


Where k=Proportionality constant

K remain constant when x and y are in direct proportion
From first table




When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.
From second table
not ]define

It is not direct proportion because k does not remain constant.
From third table


It is not direct proportion because k does not remain constant.
