Suppose y varies directly with x. if y = 6 when x = -2, find x when y = 15.
a. ⅕
b. 5
c. -5
d. -⅕

C. -5

Step-by-step explanation:

Since, y varies directly with x,

⇒ y ∝ x

⇒ y = kx -----(1)

Where k is the constant of proportionality,

Given,

y = 6 when x = - 2,

From equation (1),

Again from equation (1),

y = - 3x

If y = 15,

Hence, option C is correct.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
