115) recall that a map f: x y is an open map if for every set u that is open in x, the set (u) is open in y. which of the statements () of theorem 7.2 remain true if one replaces the word "continuous" throughout by the word open"?

y = 56

the initial statement is y varies as

to convert to an equation multiply by k the constant of variation

y =

y = 96 when a = 8 , b = 6 , c = 16

y =

hence k =

            = = = 8

thus y =

given a = 7 , b = 5 , c = 25 then

y = = 8 × 7 = 56

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
