I looked it up
The line y=-x-3 begins in Q II and ends in Q IV. Since you have the "equal to or greater than" operator, the shaded area is ABOVE this line, and the line itself is dark (shaded) because of the "equal to."
The number of blue roses will be 72. Then the number of red roses that she have at first is 84.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Mrs Fernandez has a total of 156 red and blue roses.
After selling the same number of red and blue roses.
She had 1/3 of the number of red roses and 2/9 of the number of blue roses left.
Let x be the number of red rose and y be the number of blue roses.
Then the equation will be
x + y = 156 ...1
2x/3 = 7y/9
6x = 7y ...2
By solving the equations 1 and 2, we have
x = 84 and y = 72
Then the number of red roses that she have at first is 84.
