3. If x and y vary directly, and x = 60 when y = 5, what is the value of у when x = 36 ?

y = 3

Step-by-step explanation:

Use the direct variation equation, y = kx

Plug in 60 as x and 5 as y, and solve for k

y = kx

5 = k(60)

1/12 = k

So, the equation is y = 1/12x

Plug in 36 as x and solve for y

y = 1/12x

y = 1/12(36)

y = 3

So, when x = 36, y = 3

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
