Which of the following are true statements about the expression 5 + (-5) 1. the expression equals 0.
2. The expression equals 10.
3. The expression describes the number that is 5 to the left of 5 on the number line.
4. The expression describes the number that is 5 to the right of 5 on the number line.

Answers

Answer:

\huge\boxed{\sf The \ expression\ equals \ zero}

Step-by-step explanation:

=> 5 + (-5)    [ + (-) = - ]

=> 5 - 5

=> Zero

Final answer:

The expression 5 + (-5) equals 0 and describes the number that is 5 to the left of 5 on the number line.

Explanation:

The true statements about the expression 5 + (-5) are:

  1. The expression equals 0.
  2. The expression describes the number that is 5 to the left of 5 on the number line.

When we add a positive number and a negative number with equal magnitudes, the result is always 0. In this case, 5 + (-5) equals 0. Alternatively, we can interpret the expression as starting from 5 and moving 5 units to the left (in the negative direction), which also leads to 0 on the number line.

so F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40 
10 dollars for every mile over and m=miles over so put them all toghether and get
F(m)=10m+40


1.
so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph
