A teacher is organizing her school supllies. she noticed that for every 2 pencils she has 7 pens. If she has 35 pens how many pencils does she have

10

Step-by-step explanation:

because 7÷35 =5 but that would be for only one pencil so if u multiply that 5×2 it would be 10 pencils

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

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
