Question

4x-4<20 and -6x+7>5 it also wants me to graph the set and write it in interval notation

Answer 1

First, let's simplify:
4x-4<20
Add 4 to both sides
4x<24
Divide by 4
x<6



OK, next equation:
-6x+7>5
Subtract 7 from both sides
-6x>-2
Now, divide by -6. Remember that dividing by a negative will switch the direction of the sign
x<1/3



You can use desmos graphing calculator to graph the set. Make sure that you shade to the left, and use a dotted line for your assignment.
