Brandy went mountain climbing. she ascended 20 feet above sea level and then descended 5 feet. determine the opposite of the height brandy descended. how do you know the value you chose is the opposite?

  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.

it is x=-4

step-by-step explanation:

180-142=38 for the acute angle next to the entry

90+38=128
