Which equation, when solved, results in a different value of x than the other three? Negative StartFraction 7 over 8 EndFraction x minus three-fourths = 20 Three-fourths + StartFraction 7 over 8 EndFraction x = negative 20 Negative 7 (StartFraction 1 over 8 EndFraction) x minus three-fourths = 20 Negative StartFraction 7 over 8 EndFraction (Negative StartFraction 8 over 7 EndFraction) x minus three-fourths = 20 (Negative StartFraction 8 over 7 EndFraction)

7 (StartFraction x over 8 EndFraction) + three-fourths = negative 6

Step-by-step explanation:

7  X+3

8       4=-6

ci

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
