Determine if the expression —4 – 5r4 – 2r3 is a polynomial or not. if it is a
polynomial, state the type and degree of the polynomimal.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

b

step-by-step explanation:

y-y1=m(x-x1)

y-1=1(x-8)

the answer should be 3.54 g/cm^3
