False.  The value of theta is the angle measured counterclockwise that the vector makes with respect to the positive x-axis.

Answer:

False

Step-by-step explanation:

In polar coordinates, a point on a plane is represented by P = (r, theta), where r is the radial coordinate and represents the distance from the point to the origin, and theta is the counterclockwise angle formed between the positive x-axis and the segment formed between P and the origin.

The coordinate grid shows points a through k. Which points are solutions to the system of inequalities 2x+y 8 please help this i
andre [41]

Answer:

The points that verify the system of inequalities are:

point E, pointF, and point G.

Step-by-step explanation:

Please see the attached image that illustrates the boundary lines in your system of inequalities.

The boundary line for the inequality 2x+y is depicted in green, while the boundary line for the inequality 2x-4y>8 is depicted in red.

By solving for y in each inequality, we understand which half-plane should be considered for the inequality:

First inequality (green boundary line) :

2x+y

This means that we are to consider the points below the green boundary line.

Second inequality (red boundary line) :

2x-4y >8\\2x-8>4y\\y

This means we have to consider the points below the red boundary line.

Recall as well that both conditions we arrived at have to be satisfied by the points that are solutions of both inequalities.

From the image, we can see that there are only three points that reside at the same time below the green and the red boundary lines. These points are: point E, pointF, and point G.

On the other hand, we have two points that lie on a boundary line (point J and H), but they should be ignored, since the system of inequalities contain just inequality symbols < or >, and not the "equal" sign.

-65=6b-11<br><br> hi I don't understand how to solve this equation<br> can someone please explain :)
belka [17]
-65=6b-11

Add 11 to both sides to get rid of the -11 on the right side

-54=6b

Then divide both sides by six to find the value of b

-9=b

So b is -9
