Step-by-step explanation:

Subject: Re: Need the math proof for 1 + 1 = 2

The proof starts from the Peano Postulates, which define the natural

numbers N. N is the smallest set satisfying these postulates:

P1. 1 is in N.

P2. If x is in N, then its "successor" x' is in N.

P3. There is no x such that x' = 1.

P4. If x isn't 1, then there is a y in N such that y' = x.

P5. If S is a subset of N, 1 is in S, and the implication

(x in S => x' in S) holds, then S = N.

Then you have to define addition recursively:

Def: Let a and b be in N. If b = 1, then define a + b = a'

(using P1 and P2). If b isn't 1, then let c' = b, with c in N

(using P4), and define a + b = (a + c)'.

Then you have to define 2:

Def: 2 = 1'

2 is in N by P1, P2, and the definition of 2.

Theorem: 1 + 1 = 2

Proof: Use the first part of the definition of + with a = b = 1.

Then 1 + 1 = 1' = 2 Q.E.D.

Note: There is an alternate formulation of the Peano Postulates which

replaces 1 with 0 in P1, P3, P4, and P5. Then you have to change the

definition of addition to this:

Def: Let a and b be in N. If b = 0, then define a + b = a.

If b isn't 0, then let c' = b, with c in N, and define

a + b = (a + c)'.

You also have to define 1 = 0', and 2 = 1'. Then the proof of the

Theorem above is a little different:

Proof: Use the second part of the definition of + first:

1 + 1 = (1 + 0)'

Now use the first part of the definition of + on the sum in

parentheses: 1 + 1 = (1)' = 1' = 2 Q.E.D.

*for the symmetrical hexagon you can rotate it one angle and it'll look unmoved.

*for the 4 since it's not symmetrical you need to do a complete rotation or not move it at all. so either 360° or 0°

Answer:

find the LCM of denominators and multiply the last answers of LCM for example take 1/3 and 1/2 it's LCM is 6

1/3 = 1×2/3×2 = 2/6

1/2 = 1×3/2×3 = 3/6

then subtract 3-2/6 = 1/6 this is subtraction

instead of subtracting just add it

Answer:

D. Lines e and f are parallel because their same side exterior angles are supplementary.

Step-by-step explanation:

I know for a fact that it is not C or A even though those ones would make the most sense. This leaves B and D; It's not B because is said that angles A and B are both exterior which is incorrect, A in interior and B is Exterior. This leaves us with D as our final answer.

Hope this helps, may I get brainliest please? :)

The parallel lines are; Lines e and f are parallel because their same side exterior angles are supplementary.

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the given parallel line has equation y = 4x + 2, thus its slope is 4 and thus, the slope of the needed line is 4.

We have given that Lines e and f are intersected by lines a and b.

At the intersection of lines a and e, the uppercase right angle is 110 degrees. The lines b and e, the uppercase right angle is 110 degrees. The lines b and f, the bottom right angle is 80 degrees.

Therefore, The parallel lines is; Lines e and f are parallel because their same side exterior angles are supplementary.

Answer:

3.99=4

Step-by-step explanation:

Part A

distance of point 1 = -1.6

distance of point 2 = 0.3

difference: -1.6 - 0.3 = -1.9

distance: 0.3-(-1.6) = 1.9

The expression that represents the distance between the two points is |0.3 + 1.6| and the distance between the two points is 1.9 units

The points on the line are represented as:

Point 1 = 0.3

Point 2 = -1.6

The distance between the two points is calculated using the following absolute value equation

d = |Point 1 - Point 2|

Substitute the known values

d = |0.3 - -1.6|

This gives

d = |0.3 + 1.6|

Hence, the expression that represents the distance between the two points is |0.3 + 1.6|

In (a), we have:

d = |0.3 + 1.6|

Evaluate the sum

d = |1.9|

Remove the absolute sign

d = 1.9

Hence, the distance between the two points is 1.9 units
