-El tiempo que tardan en hacer un trabajo un grupo de personas, está en función de la cantidad que son. Suponiendo que trabajan al mismo ritmo. Diez trabajadores realizan un trabajo en diez días. ¿Cuántos días tardarán ocho? A) 8
B) 10
C) 12.5
D) 16
​

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

graph of this function as shown below:

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

i can't solve unless i know what the line is

welcome to/p>

probably .5

i can on others if necessary.
