Sam and Dillon want to do a prank on Mrs. Burke. The two pranksters need AT LEAST 200 cans of fart spray to fill the room. The normal fart spray costs 10 dollars but double stinky fart spray is 20 dollars. Sam is broke, but Dillon has $400 to spend on fart spray, but no more than that. Write a system of inequalities to represent the problem. Use x and y.
x+y ≥ 200 and 10x + 20y ≤ 400
Solving Inequalities
Solve for x.
-9x + 1 > -71
What is:
x > -8
What is the inequality used for this graph?
y ≥ x-3
Draw a number line and plot the inequality
-9 < x ≤ 4
Jenny wants to bankrupt her husband. To do this she must spend OVER 600 dollars. If a pair of pants costs 12 dollars, and a shirt costs 10 dollars, then write an inequality to represent the problem that will bankrupt her husband.
12x + 10y > 600
Solve an Inequality
8 < 4d + 12 < 32
-1 < d < 5
Write the system of inequalities that the graph represents.
y>-2x and y≤1/2x-4
Solve
3(x – 2) + 4 > 2(2x – 3)
What is x < 4
You can work a total of no more then 41 hours each week at your two jobs. Housecleaning pays $5 per hour and your sales job pays $8 per hour. You need to earn at least $254 each week to pay your bills. Write a system of inequalities that shows the various numbers of hours you can work at each job.
What is Hours: x + y ≤ 41
Money: 5x + 8y ≥ 254
Solve the inequality
p - 2< -2 OR p - 2 > 1
p < 0 OR p > 3
Graph the inequalities:
y ≥ 3x+2 and y ≤ x-2
If you graphed this inequality, would the line be dashed or solid?
y>2x-3
It would be a dashed line
Mary babysits for $4 per hour. She also works as a tutor for $7 per hour. She is only allowed to work 13 hours per week. She wants to make at least $65. What is the least amount of hours she can work?
