Suppose y varies directly with x, and y = 45 when x = 3. What is the value of y when x = -6?

y=-90

Step-by-step explanation:

y = kx

45 = k 3

k = 15

y = 15*-6

y=-90

36

We should write a formula for their relationship:

Y = x+42. <- this is what a direct varieation is I believe.

So, when x is -6, y is +42 aka 36

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
