WebSo, here's my tip: when looking to find the graph of an inequality, look at inequality sign first. If it has a line directly below it, it is deemed inclusive, indicating a solid line. If there is no line under the inequality sign, it is deemed non-inclusive, indicating a dashed line. WebThe graph of this inequality will have two closed circles, at 4 and −4 − 4. The distance between these two values on the number line is colored in blue because all of these values satisfy the inequality. The solution can be written this way: Inequality: −4 ≤x ≤4 − 4 ≤ x ≤ 4 Interval: [−4,4] [ − 4, 4]

WebThe types of regions we will consider in this explainer are the ones defined in terms of inequalities such as 𝑧 − 𝑧 𝑟 and composite regions defined in terms of multiple inequalities. For example, let us consider the region defined by 𝑧 + 1 + 𝑖 2. To represent this on an Argand diagram, we first consider the circle defined by 𝑧 + 1 + 𝑖 = 2. WebTo represent inequalities on a number line we show the range of numbers by drawing a straight line and indicating the end points with either an open circle or a closed circle. … candlechaseapts.com

WebOct 9, 2024 · Chose the inequality shown by this diagram - 28820442. 8. You have a coupon for $2 off any purchase at the supermarket. Write an equation to represent the … WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4. WebKey Concepts Inequalities, like equations, have solutions. An arrow on the number line—pointing to the right for greater values and to the left for lesser values—can be used to show that there are infinitely many solutions to an inequality. fish restaurant auckland
