10 < –2b or 2b + 3 > 11

<span>10 < –2b or 2b + 3 > 11 represents 2 different sets of numbers.

</span><span>10 < –2b can be reduced by dividing both sides by -2; you must then reverse the direction of the < sign:  -5 > b, which is the interval b < -5:  (-infinity, -5).

</span>2b + 3 > 11 reduces to 2b > 8, which in turn reduces to b > 4:  (4, infinity).

It may be helpful to graph these sets.

If you really do mean   "<span>10 < –2b or 2b + 3 > 11," then the "solution" is made up of two sub-intervals:  b < -5 and b > 4.

The pool is located at (0,0) to get to your house from the pool you walk three blocks west and one block north what ordered pair
ira [324]

Answer:

(-3, 1) quadrant II (2)

Step-by-step explanation:

An image of the coordinate plane is show.  The quadrants start at the top right and move around in the counter-clockwise direction.  The x-axis is horizontal (side to side) and y-axis is vertical (up and down).  Starting at the origin of the coordinate plane (0, 0) and going three blocks west (left) would put you at -3 on the x-axis.  If you then proceed to go north (up) +1, you would now be at point (-3, 1) which is a (-x, +y)  or in quadrant II.

To start off, simplify the equation if needed:
3m>=21
Since both sides are divisible by 3, you can simplify for the equation to be

m>=7

Next is to find the domain of the line graph. Since the sign is more than or equal to (>=), the circle is closed.
And since m is MORE THAN OR EQUAL TO, the section starts at 7 (closed circle), and continues after. Therefore, your answer will be the third selection.
