Solve and graph the inequality |4 – v| < 5.
a. write the inequality as two inequalities without absolute value.
4-v< 5
4-v> 5

b. solve the inequality and write the solution set.

c. graph the solution on a number line.

** i can graph it, i just need for b **

OK so when you have absolute values it is very useful to think of abs(4 - v) as the distance between 4 and v. Then you can write abs(4-v) < 5 as -5 < 4 - v < 5 This is because the distance between these two points must be in this range. Try writing out a real number line and giving random values to v. You will be able to see how this rule works! Now that we have -5 < 4 - v < 5 we can solve it using basic algebra. We can solve it just like a normal equation but instead of doing an operation on "both sides" we have to do an operation on all three sides :D -5 < 4 - v < 5 -5 -4 < 4 - v - 4 < 5 -4 add - 4 to all three sides -9 <-v <1 simplify -1 * -9 > -1 * -v > -1 * 1 multiply by -1 DONT FORGET TO SWITCH INEQUALITIES 9 > v > -1 -1 < v < 9 now just make sure you show in your number line what numbers v can be.

Idon’t actually know but have you asked google yet

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
