Which statement describes the system of equations?
(3x-4y=-35
(3x + 4y = 5

It has one solution (-5.5).

It has one solution (5, -5).

The system has no solution.

The system has infinitely many solutions.

one solution

Step-by-step explanation:

3x - 4y = -35

3x + 4y = 5

6x = -30

x = -5

3(-5) + 4y = 5

-15 + 4y = 5

4y = 20

y = 5

(-5, 5)

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
