Algebra 1 Warm Ups 10/30

10/30 Graph y > 3x 2. Graph 3x + 5y = 10

10/31 Graph 2x + y > -3 2. 3. Simplify the radical:

11/1 Brandon has twice as much money as Matthew. Matthew has $8 less than Joe. Together, they have $84. Let x represent the amount of money Joe has. Write an expression to determine how much money Joe has. 2. Write the inequality that matches the graph: 3. A manufacturer keeps track of her monthly costs by using a “cost function” that assigns a total cost for a given number of manufactured items, x. The function is C(x) = 4735 + 1.45x. What is a reasonable domain for this function?

11/2 Name the domain and range of the function ----->. 2. Coach Peavey buys muffins to sell each week. The cost of the muffins is $75. He charges $1.50 per muffin. He calculates his profit by finding the difference of total sales and cost. Write a function that models the amount of profit he can make each week, where m if the number of muffins sold. 3. The table shows the distance a car has traveled. What is the meaning of the slope of the data? Minutes 25 50 75 100 Distance 20 40 60 80

Ticket out the door 11/1 Answer the following. What is the range? On what interval is the graph increasing? On what interval is the graph decreasing? As x approaches infinity, f(x) approaches…..
