The system of equations is graphed on the coordinate plane.
1 answer:
The solution is: (-1,-2)
Step-by-step explanation:
Given equations are:
In order to solve two equations with graphing method, the graphs of two equations are made which are straight lines the point of intersection is the solution of the equations.
Here,
The graph is given
To read the solution of the graph we see that on which x and y- coordinates the point of intersection is. then the answer is written as (x-coordinate , y-coordinate)
The solution point is highlighted with a circle. The x-coordinate is -1 and y-coordinate is -2
So,
The solution is: (-1,-2)

Answer:
The correct answer is marked.
Step-by-step explanation:
The solution is easily found using synthetic division. The attachment shows how that is done, and what the result is.
Answer:
45°
Step-by-step explanation:
The hour hand makes a trip of 360° around the face of the clock in 12 hours, so in 4.5 hours will make an angle of ...
... (4.5/12)·360° = 135°
clockwise from straight up.
The minute hand makes that 360° turn in 1 hour, so in 30 minutes, it will be 180° clockwise from straight up.
The difference between the angles of the hands is ...
... 180° -135° = 45°
