WebExample 2.69. Solve the inequality 7 y < 42, graph the solution on the number line, and write the solution in interval notation. Divide both sides of the inequality by 7. Since 7 > 0 7 > 0, the inequality stays the same. Simplify. Graph the solution on the number line. Write the solution in interval notation. WebSolving Equations Involving a Single Trigonometric Function. When we are given equations that involve only one of the six trigonometric functions, their solutions involve using algebraic techniques and the unit circle (see Figure 2).We need to make several considerations when the equation involves trigonometric functions other than sine and …

Web9.5 Linear Inequalities in Two Variables An inequality of any of the forms ax+by+c<0 ax+by+c<=0 ax+by+c>0 ax+by+c>=0 with a and b not both zero is called a linear inequality in two variables. The solution set of such an inequality is one of the two half-planes determined by the line ax+ by + c = 0. 2x-y+2<0 Web17. Solve: (4x – 10)/3 ≤ (5x – 7)/2, x ∈ R and represent the solution set on the number line. ... 29. If x ∈ I, find the smallest value of x which satisfies the inequation Solution: ... Find the solution set of the inequation x + 5 ≤ 2x + 3; x ∈ R. Graph the solution set on the number line. Solution: Given inequation, x + 5 ≤ 2x ... WebGraph x + 2y = 4. Solution We first solve for y in terms of x to get. We now select any two values of x to find the associated values of y. We will use 2 and 0 for x. Thus, two solutions of the equation are (2, 1) and (0, 2). Next, we graph these ordered pairs and pass a straight line through the points, as shown in the figure. defender commercial vehicles
