Which of these equations could represent the relationship between V1 and V2?

V1 = MULTIPLIER \cdot V2

STATEMENT if V1 = k \cdot V2 for some constant k

V1 = MULTIPLIER \cdot V2 fits this pattern, with k = MULTIPLIER.

  • V1 \cdot V2 = MULTIPLIER
  • V1 \cdot V2 = MULTIPLIER_INVERSE
  • V1 = MULTIPLIER \cdot \frac{1}{V2}
  • MULTIPLIER \cdot V1 = \frac{1}{V2}
  • MULTIPLIER_INVERSE \cdot V1 = \frac{1}{V2}
  • MULTIPLIER \cdot \frac{1}{V1} = V2
  • MULTIPLIER_INVERSE \cdot \frac{1}{V1} = V2
  • V1 + V2 = MULTIPLIER_INVERSE
  • V1 = MULTIPLIER - V2

\frac{V1}{V2} = MULTIPLIER

STATEMENT if V1 = k \cdot V2 for some constant k

If you divide each side of this expression by V2, you get \dfrac{V1}{V2} = k for some constant k.

\dfrac{V1}{V2} = MULTIPLIER fits this pattern, with k = MULTIPLIER.

MULTIPLIER \cdot V1 = V2

STATEMENT if V1 = k \cdot V2 for some constant k

If you divide each side of this expression by k, you get \dfrac{1}{k} \cdot V1 = V2.

MULTIPLIER \cdot V1 = V2 fits this pattern, with k = MULTIPLIER_INVERSE.

STATEMENT if V1 = k \cdot \dfrac{1}{V2} for some constant k

If you multiply each side of this expression by V2, you get V1 \cdot V2 = k for some constant k.

V1 \cdot V2 = MULTIPLIER fits this pattern, with k = MULTIPLIER.

MULTIPLIER \cdot \dfrac{1}{V1} = V2

STATEMENT if V1 = k \cdot \dfrac{1}{V2} for some constant k

If you divide each side of this expression by k, you get \dfrac{V1}{k} = \dfrac{1}{V2}.

Then you can take the inverse of each side to get \dfrac{k}{V1} = V2.

MULTIPLIER \cdot \dfrac{1}{V1} = V2 fits this pattern, with k = MULTIPLIER.
