An archeologist in turkey discovers a spear head that contains 32% of its original amount of c-14. find the age of the spear head to the nearest year.

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

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

47 - 90 = 43

43 - 180 = x

x = 137

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
