System linear inequalities word problemsCovid19 has led the world to go through a phenomenal transition . Elearning is the future today. Stay Home , Stay Safe and keep learning!!! When you learn Algebra 1 in higher class you will find that real word problems are more difficult. There are more steps to find the solution. You have already studied systems of inequalities. Here we will discuss System linear inequalities word problems.From the given word problems, Step 1 : Read the question properly. Step 2 : Check the inequalities given in the question. Step 3 : According to the inequality, make an inequations. step 4: Change the given equation in slope intercept form. Step 5 : Graph the each line While graphing check the origin test and then mark each region. Step 6 : Intersecting region is the solution. Examples on solving Linear Inequalities word problemsWrite an inequality for each of the following .1)Fuel from petrol pump A costs 3 per gallon and from petrol pump B costs 5 per gallon. Mr.S have at most 20 to spend on fuel. Write and graph a system of linear inequalities. Solution : Let fuel from petrol pump A = x and from petrol pump B = y Mr. S have at most 20. ∴ 3x + 5y $\leq$ 20 As the fuel never be negative so, x $\geq$ 0 y $\geq$ 0 As both x and y are greater than zero so zero is included. The 4th center graph represents the solution region. Any coordinates from that region satisfies the inequality. Such as (3,2) ,(2,2) etc. 2) Anita works as a online tutor for $\$ $4 per hour. She also works as a editor for $\$ $7 per hour. She is only allowed to work 15 hours per week. She wants to make at most $\$ $75. Graph a system of inequalities to represent this situation and write at least two solutions. Solution: Let works as a online tutor = x and as an editor be y. 4x + 7y $\leq$ 75 x + y $\leq$ 15 The center graph represents the intersecting region. The coordinates (2,4) and (6,6) satisfies the inequalities. Check : (2,4) ⇒ 2(4) + 7(4) = 36 $\leq$ 74 2 + 4 = 6 $\leq$ 15 And (6,6) ⇒ 2(6) + 7(6) = 57 $\leq$ 74 6 + 6 = 12 $\leq$ 15 From system of linear inequalities word problems to Home Covid19 has affected physical interactions between people.
