1.a function is a relation in which each input has only one output.

true or false

2.what are the ways a function can be represented

sets of ordered pairs

tables

arrow diagrams

graphs

equations

3.what does the graph of a function in the form y=mx+b look like?

line

point

parabola

circle

1.) True

2.) - tables - graphs - equations (I guess all of above)

3.) line

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
