Will mark brainliest ! < 3 sylvain spent a total of 18 hours on english and math homework over the last 3 weeks. he spent twice as much time on english than on math. let x represent the number of hours spent on english and y represent the number of hours spent on math. x+y=18 x=2y what is the solution of the system of equations? a)(12, 6) b)(6, 12) c)(9, 9) d)(15, 3)lolll i got the answer it was a.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

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:
