Which ordered pair is a solution of the equation? 3x+3y=-x+5y choose 1 a. only (1,2) b. (2,4) c. both (1,2) and (2,4) d. neither

⭐Hola User

⭐Here is your Answer..!!

⭐

↪Actually welcome to the concept of the Linear Equation in two variables..

↪Basically here the given equation is ..

↪3x+3y = -x+5y

↪substituing (1,2) ,we get as

↪3(1) +3 (2) = -1 + 5 (2)

↪=》 9 = 9 .. thus it is a solution

↪substituing (2,4) , we get as ..

↪3 (2) + 3 (4) = -2 + 5 (4)

↪=》 18 = 18 ...thus this is also a solution..

↪therefore. ..

↪C.) both (1,2) and (2,4) are the solutions

The constant presence of diseases or infectious agents within a given geographic area or population group. it may also refer to the usual prevalence of a given disease with such area or group. it includes holoendemic and hyperendemic diseases. a holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holoendemic disease). a hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. so probably family history.
