Answer:
Step-by-step explanation:
First we need to determine the equation of the boundary line.
The line has y-intercept of c=7 and slope .
The slope is given by y=mx+c.
We substitute the slope and intercept to get:
.
Since the lower half plane is shaded, with the boundary being a dashed line, the required inequality is

Answer:
Step-by-step explanation:
The given equation is in the form
We have to evaluate the correct system of equations which can be used to find the roots of the equation.
We can find the root of the equation by plotting the graph of the equations. In order to graph, we can assume the left and right hand side of the given equation as two separate equations.
Therefore, we have
Now, we plot the graph of these two equations in the same coordinate plane. The intersection point (s) would be the roots of the given equation.
Hence, the system of equation that we can use to find the root of the given equation is
Last option is correct.
