You need to cross a canal and want to determine the distance across the opposite side. Since you're able to take
measurements on your side of the canal, you come up with 40
ft. and 16 ft. Find the distance x across the canal. Show all work.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

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

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
