Do you mean on a graph or number line?
Can somebody please show me how to graph inequalities? I don't get it and my homework is way late so please HELP!
x>4 - graph the solution for each set of inequalities
3x[U]>2x-4 - solve and graph the solution set of each inequalities
I just need for someone to show and explain how to do these and I can try to do the rest on my own. Any help will be greatly appreciated THANKS
Hello, foofergutierrez!
You should be familiar with Solving Inequalities.
Solve for the variable as you would with an equation except:
. . when multiplying or dividing by a negative, reverse the inequality.
Graph the solution for: .
This is the set of all numbers greater than 4.
. . .
. . . . . . . . .
The circle indicates that the is not included.
Graph the solution for: .
Solve for
This is the set of all numbers greater than or equal to
. . .
. . . . .
The solid dot indicates that the is included.
Ok I kind of understand what to do but here are some other practice equations I would like to see done before my attempt to work my problems so that I know that I am doing them right.
7(x-3>5x-14
2(x+28)<6(x)
I also have this weird word problem that I cannot make any sense of.
The cost for a long distance call is $.36 for the first minute and $.21 for each additional minute. Write an equality representing the number of minutes a person could talk without exceeding $3.00.
Again, I thank all who can help me and if I could I would pay ou back somehow! You guys are awesome!!!
Hello again, foofergutierrez!
The cost for a long distance call is $0.36 for the first minute
and $0.21 for each additional minute.
Write an equality representing the number of minutes a person could talk
without exceeding $3.00.
Let be the number of minutes we can talk for $3.00 or less.
We are charged for the first minute.
We are charged each for the other minutes.
. . This costs us: . cents.
Hence, the total charge is: . cents
Since we do not want to exceed $3
. . we have: .
Solve for
. . . . . . . . . . . . .
. . . . . . . . . . . . . . . .
. . . . . . . . . . . . . . . . . .
Therefore, we can talk up to 13 minutes without going over the $3 limit.
