I need help to find the proof

Prove by contradiction: If an integer n has the form 3K+1, then it does not have the form 9L+5.

Find an example of a set A and functions f :A→A and g:A→A such that f◦g=idA but g ◦ f does not equal idA. I am not sure what idA means or an example for this

If all the primes where (2,3,5) then you can multiply them together to get 30, but then you add 1. Like how 64 is made up of 2x2x2x2x2x2, which can't this new number be made up of multiple smaller...

I have a lot of trouble with proofs and need help.

I can't figure out how to prove that statement. Any help would be great.

The picture is a quadrilateral with point A on the bottom left corner, point B on the bottom right corner, point D on the top left corner, point C on the top right corner, with a diagonal line from...

Write a proof using the following information. Given: ∠EAB ≅ ∠DBA, ∠DAE ≅ ∠CBD Prove: DA ≅ EB

2 Let a and b be integers such that a divides b+2 and a divides c-1. (a) Prove that a divides bc+2 Let a, b and c be integers such that a divides b and a divides c. Let x...

Full Question: The coordinates for a rhombus are given (2a, 0), (0, 2b), (-2a, 0), (0,-2b). Write a plan to prove that the midpoints of the sides of a rhombus determine a rectangle using coordinate geometry...

T is the midpoint of line rv t is the midpoint of line su line rs is congruent to line su

I know to like assume that (x^5)+(e^x)=0 has two distinct roots and then find the contradiction. But am stuck.

Given: AD = CD DB bisects AC Prove: Triangle ADB = Triangle CDB

Given: B is the midpoint of AC and DL Prove: Triangle ADB and Triangle CLB are congruent

Statements: 9 = 4x - 3(x - 2) 9 = 4x - 3x + 6 9 = x + 6 3 = x x = 3 Reasons: Given ...

Hello. I have a question about a two column proof. It is given that angle 1 and angle 2 are congruent to each other. We have to prove that angle 3 and angle 4 are congruent. For reference, look at...

Statements: m ⊥ l, n ⊥ l <1 is a right angle <2 is a right angle <1 =~ <2 m || n Reasons: Given ...

** Will need 3 steps. If m<1 = 40° and m<2 = 50°, then the angles are complementary.

Could you prove and explain how you did it/ what properties you used. A____L_________S____K <---- Line Segment
