PLZZZ HELP ME OUT THIS DUE RIGHT NOW AND I FREAKING OUT PLEASE HELP ME P. S YOU HAVE WRITE ANSWERS FOR ALL OF THEM Task 1 – Operations on the Number Line
(Variation of the above task)
A number line is shown below. The numbers 0 and 1are marked on the line, as are two other numbers a and b.

For each of the following expressions determine if the answer would be positive, negative, or zero. For each one PROVE HOW YOU KNOW.

1. a−1


Explanation:

2. a−2


Explanation:

3. b−1


Explanation:

4. -b−b


Explanation:

5. a−b

Explanation:

6. ab+1

Explanation:

7. b− a

Explanation:

8. a a-b x b


Explanation:

a is greater than 1, so a−1 is positive.

Step-by-step explanation:

5.6%

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
