Give the equation for each of the following statements.
emmasim [6.3K]

Answer:

Step-by-step explanation:

1. Y varies jointly as R and T

Y = k*R*T

Y = kRT

Where,

k = constant of proportionality

2. B is directly proportional to the square of A and inversely proportional to the cube of C.​

B = k(A²) / C³

B = kA²/C³

Where,

k = constant of proportionality

If y varies directly as x and y = 3 when x = - 9, then find x when y = 5.
Rus_ich [418]

Answer:

d. - 15

Step-by-step explanation:

The equation for direct variation is

y = kx

We know y =3 when x = -9

3 = k(-9)

Divide by -9

3/-9 = -9k/-9

-1/3 = k

The equation is then

y = -1/3 x

We know y = 5

5 = -1/3 x

Multiply each side by -3

-3*5 = -3*-1/3x

-15 = x
