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:

The expression equals 0.
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.

Which letter in the word happy has an order 2 rotational symmetry

Answers

The letter H is the only one in the word "happy" that has the rotational simmetry on the order of two. In fact, if you rotate the letter H 180° clockwise or counterwise, it will still look the same; it is called "on the order of two", exactly because you've rotated it 180° (two rotations of 90°).

Answer

Letter H

Explanation
The order of symmetry is the number times an object appears exactly the same when rotated about a certain axis.
From the word HAPPY, only letter H will have 2 order of symmetry.
When rotated at 180°, It will look exactly the same.
A, P, P and Y have only 1 order of symmetry.
