Answer: y+ 7 = 5x
Step-by-step explanation:
A linear function is a function in which the highest power of the unknown is 1 , that is , the highest power of the variables that are unknown will be 1.
From the question given:
A : 1 - 
= -y
The power of x is 2 , though the power of y is 1 but because of the existence of the power of x which is 2 , it is not linear
B : y + 7 = 5x
both the power of x and y is 1 , so it is a linear function
C: 
+ 4 = y is not linear
D is also not linear
likewise , E is not linear
Therefore , B is the only linear function
We are required to find the total milligrams if medicine the hospital can get from the three companies.
The total quantity of medicine the hospital can get from the three companies is 2.75 milligrams
There are there companies:
Company A
Company B
Company C
Company A = 1.3 milligrams
Company A is 0.9 milligrams more than Company C's
A = 0.9 + C
1.3 = 0.9 + C
1.3 - 0.9 = C
0.4 = C
C = 0.4 milligrams
Company A is also twice the difference between the weight of
Company B's supply and Company C's
A = 2(B - C)
1.3 = 2(B - 0.4)
1.3 = 2B - 0.8
1.3 + 0.8 = 2B
2.1 = 2B
Divide both sides by 2
B = 2.1/2
B = 1.05 milligrams
Therefore,
A + B + C
= 1.3 + 1.05 + 0.4
= 2.75 milligrams
