On Saturday morning, Josh spends 3/4 of an hour watching TV.
In the evening he spends 1/2
an hour watching TV.
How long does he spend watching TV on Saturday?

75 mins / 1 hour 15 mins

Step-by-step explanation:

3/4 of an hour is 45 mins

1/2 an hour is 30 mins

30 + 45 = 75 mins / 1 hour 15 mins

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
