Does the following system have a unique solution? Why? (6x-8y = 5
1-3x + 4y = -4

1. Yes because the determinant of the coefficient matrix is 0

2. Yes because the determinant of the coefficient matrix is 24

3. No because the determinant of the coefficient matrix is 0

4. No because the determinant of the coefficient matrix is 24

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 is  

c.
