Kyle says he can pick any number between 1 and 100, add 1 to it, multiply the result by 2, add two to that result, then subtract 2 times the number he started with, and he will always get the same number that he started with.
part a: using x to represent between 1 and 100, write and equation that models the process described above

part b: is kyle correct? (can you perform the operations mentioned above and always get the same number back that you started with?) show your work.

(this is a study sheet, i need help) thanks!!

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
