Question

Select all of the equations that represent proportional realtionships. A. C = 2p + 6 B. T = 2.5d C. F = 9/5 C + 32 D. C = 2.54n E. E = 12s F. SA = 6s2 G. V = s3

Answer 1

Options (B), (D), (E), (F) and (G)

Explanation:

Any equation in the form of 'y = mx' shows the proportional relationship.

Or functions passing through origin show the proportional relationship.

Where 'm' = Proportionality constant

Now by analyzing the given options,

Option A

C = 2p + 6

Not proportional.

Option B

T = 2.5 D

Proportional.

(Proportionality constant = 2.5)

Option C

F =
`(9)/(5)C+32`

Not proportional

Option D

C = 2.54n

Proportional.

Option E

E = 2s

Proportional

Option F

S.A. = 6s²

Proportional.

Option G

Volume (V) = s³

Not Proportional.

Options (B), (D), (E), (F) and (G) are the correct options.
