The number of milk bottles sold can be determined by the equation:

P 0.35n, where P is the number of bottles of milk and n is the number of

boxes opened. What is the constant of proportionality (unit rate)?

option d is correct x = –10, x = –5, or x = 5    

step-by-step explanation:

given : function -

one root x=-10

the remainder theorem : solve the polynomial through long division.

using formula   p(x) = (x – a) q(x)   +   r(x).

where, p(x) is the dividend , (x-a) is the divisor or root , q(x) is the quotient , r(x) is the remainder

now we solve the given function using remainder theorem

,

when remainder is zero our quotient =

i.e,

solve  

therefore, roots of function is -10,5 or-5

hence, option d is correct x = –10, x = –5, or x = 5
