For Exercises 1-4, make a conjecture about whether each result will be odd or even. Use models, pictures, or other reasoning to support your conjectures. 1. an even number minus an even number 2. an odd number minus an odd number 3. an even number minus an odd number 4. an odd number minus an even number

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

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
