Graphing a solution on a number line
WebGraphing on a Number Line Integers and real numbers can be represented on a number line. The point on this line associated with each number is called the graph of the number. Notice that number lines are spaced equally, or proportionately (see Figure 1). Figure 1. Number lines. Graphing inequalities WebGraph the solution set on the number line. Then, write the solution set in the interval notation. STEP 1. Solve each inequality. First inequality: 2 + 3x > - 10 2 + 3x > −10 Subtract both sides of the inequality by 2 2. Then …

The solution set must include all possible solutions. This is why open intervals are used. They indicate that we want to start at -1, but not include it and we want all numbers up to but not including the 4. Hope this helps. 3 comments ( 14 votes) Show more...
WebOct 6, 2024 · To express the solution graphically, draw a number line and shade in all the values that are solutions to the inequality. Interval notation is textual and uses specific … WebUsing the Number Line to Solve Inequalities We can use the number line to solve inequalities containing <, ≤, >, and ≥. To solve an inequality using the number line, …
WebIn the case of the number line, positive means going to the right, while negative means going in the opposite direction, or the left. So adding/subtracting is simply about which direction you go in (right or left). An absolute value ignores that direction and simply tells you how many units or numbers away from zero something is. WebStep 4: Plug in -4 (representing the space in between the points -3 and -5 on the number line) into the (x+3) (x+5) and solve. (-4+3) (-4+5)= -1 The answer is negative. Step 5: Look at x^2+8x+15<0. The answer is suppose to be LESS than 0, which means that the answer has to be a NEGATIVE number.

Let's say for example, you plug in -1, you would always get that -1 = 1. But what if you plug in 1? You get 1 = 1. Therefore, if you solve for x , it would have both a positive and a negative answer. So, if you have a very simple equation, 2 x = 1, you would get, x = 1/2 x = -1/2 or x = 1/2 how does a pillow lava formWebThis would be the longer graph.
