Write a two-column proof for the following information. Upload your proof below. Given: M is the midpoint of CD; CM = 5x – 2; MD = 3x + 2
Prove: x= 2

Statements                                                                              Reasons

1.) M is the midpoint of CD; CM = 5x – 2; MD = 3x + 2    1.) Given

2.) CM=MD                                                                          2.) Definition of midpoint

3.) 5x-2=3x+2                                                                       3.) Substitution

4.) 2x-2=2                                                                             4.) Subtraction Property of Equality

5.) 2x=4                                                                                 5.) Subtraction Property of Equality

6.) x=2                                                                                  6.) Division Property of Equality

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
