Solve the system of equations.
3x+8y=15
2x-8y=10

x = 5

y = 0

Step-by-step explanation:

add both equations so the y-terms are eliminated and you get:

5x = 25

x = 5

substitute 5 into 'x' in one of the equations:

3(5) + 8y = 15

15 + 8y = 15

8y = 0

y = 0

nope

step-by-step explanation:

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
