Problem 38
Write each sentence as a linear inequality in two variables. Then graph the inequality. The difference between the \(x\) -variable and the \(y\) -variable is at least 3
Problem 39
Write each sentence as a linear inequality in two variables. Then graph the inequality. The difference between 5 times the \(x\) -variable and 2 times the \(y\) -variable is at most 10
Problem 48
A patient is not allowed to have more than 330 milligrams of cholesterol per day from a diet of eggs and meat. Each egg provides 165 milligrams of cholesterol. Each ounce of meat provides 110 milligrams of cholesterol. a. Write an inequality that describes the patient's dietary restrictions for \(x\) cggs and \(y\) ounces of meat. b. Graph the inequality. Because \(x\) and \(y\) must be nonnegative, limit the graph to quadrant I and its boundary only. c. Select an ordered pair satisfying the inequality. What are its coordinates and what do they represent in this situation?
Problem 49
The grade of a road or ramp refers to its slope expressed as a percent. Use this information to solve Exercises \(49-50\). Construction laws are very specific when it comes to access ramps for the disabled. Every vertical rise of 1 foot requires a horizontal run of 12 feet. What is the grade of such a ramp? Round to the nearest tenth of a percent. (GRAPH CANT COPY)
Problem 51
Graph equation. \(x=2\)
Problem 53
What does a solid line mean in the graph of an inequality?
Problem 55
Graph equation. \(y-3.5=0\)
Problem 56
Graph equation. \(y-2.5=0\)
Problem 58
Make Sense? In Exercises \(57-60\), determine whether each statement "makes sense" or "does not make sense" and explain your reasoning. When applying the slope formula, it is important to subtract corresponding coordinates in the same order.
Problem 58
Graph equation. \(y=0\)
