A student was told that AGHJ ARST and was asked to find GH. The student's work is shown below. Complete the explanation of the error and find the correct answer.
4x - 2 = 5x - 4
-2 = x - 4
2 = x
GH = 4x - 2 = 4(2) - 2 = 6 m
Since AGHJARST,
The student incorrectly identified (select)
then GH? . The length of GH is m.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
