What are the solutions of y=x^2+5x-7

You have two variables, and only one condition. It means you have infinite solutions of the form . Technically correct, probably not what you want to know.

If you wanted to know if and where the RHS crosses the x axis, the points are the solution to

If you wanted the graph it's a parabola passing through the two points we just found, (0;-7), and with an axis of equation .

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
