WebVerified answer. calculus. Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x x or y y. Draw a typical approximating rectangle and label its height and width. Then find the area of the region. x=2 y^2, \quad x=4+y^2 x= 2y2, x= 4+y2. Verified answer. WebIn solving quadratic INequalities Sal shows how you can solve for f (x) > 0 or f (x) < 0. Meaning the x coordinates at which point the f (x) line is above (>) or below (<) the x-axis (0). The two are related because the points where the f (x) line intersect the x-axis (=0) are also the same points between which the f (x) line rises above (>) or ...

WebThe first thing we want to do is manipulate the equation to get 0 on one side. To do this, we subtract 13,000 from both sides to get the following: 12,000 (2) 0.012x - 13,000 = 0. Next … WebThe graph of the solution divides the number line into three sections. Choose a value in each section and substitute it in the original inequality to see if it makes the inequality true or not. While this is not a complete check, it often helps verify the solution. ... x ≤ − 1 or x ≥ 4 x ≤ − 1 or x ≥ 4: Step 4. Graph the solution. how to reveal rows in excel

WebMar 28, 2024 · Solve and graph the solution set: − 2(4x − 5) < 9 − 2(x − 2). Solution − 2(4x − 5) < 9 − 2(x − 2) − 8x + 10 < 9 − 2x + 4 − 8x + 10 < 13 − 2x − 6x < 3 − 6x − 6 > 3 … WebThe two rules of inequalities are: If the same quantity is added to or subtracted from both sides of an inequality, the inequality remains true. If both sides of an inequality are multiplied or divided by the same positive quantity, the inequality remains true. If we multiply or divide both sides of an inequality by the same negative number, we ... Webif x = 5, y = 2(5) -6 = 4 We then note that the graph of (5, 4) also lies on the line To find solutions to an equation, as we have noted it is often easiest to first solve explicitly for y … how to reveal the whole map in dst
