Give the inequality on a number line
WebThe equation y>5 is a linear inequality equation. y=0x + 5. So whatever we put in for x, we get x*0 which always = 0. So for whatever x we use, y always equals 5. The same thing is true for y>5. y > 0x + 5. And again, no matter what x we use, y is always greater than 5. WebJan 25, 2024 · Ans: When we represent linear inequation on a number line, we use two types of dots: a solid dot and a hollow dot. To express the inequalities that have no …

WebWhen solving inequalities, like, say, this one: -2x+5<25. You would cancel out the +5 with -5 and subtract 25 by 5, so you're left with this: -2x<20. But now, since you're dividing by -2 (remember that multiplying or dividing by a negative number will reverse the sign) it will no longer be less than, it will be greater than: -2x/-2>20/-2.

WebInequalities can be graphed on a number line. Below are three examples of inequalities and their graphs. x < 2 . x ≤ − 4 . x ³ − 3 . Each of these graphs begins with a circle—either an open or closed (shaded) circle. This point is often called the end point of the solution.

WebThe circle will be open because it does not contain the 5 because x is "greater than" 5. x has to be greater than 5, so 5 is not an answer to the inequality. Now if your hand is closed around an item you can contain it within your hand. For an inequality example, let's use 2 ≥ x. the circle is closed because 2 is contained and agrees with the ...
