Anything in absolute value signs like this |-1| is positive so it would be positive 1 instead of negative. For instead question one is -1. Hope this helps you!
Answer:
V=1.3(repeating)A+1.3(repeating)M
The equation would look like
Y=-4x+7
Y=mx+b
4/20 simplified would be 1/5. You must know what simplify means first. It means to break down a fraction to its simplest form. So, to simplify 4/20, you must divide 4 from the denominator and numerator. A numerator is a number that is the number above the line. A denominator is the number on the bottom of the line.
Dividing 4 from the denominator and numerator would make it 1/5. Therefore, the answer in simplest form is 1/5. Good luck!
