Yand x have a proportional relationship, and y=12 when x=8. what is the value of x when y=18?

x = 12

Step-by-step explanation:

Proportional relationship means that = k(a constant)

Here, k = 12/8 = 3/2

So, the equation is = 3/2.

Plug in y = 18, and we get 18/x = 3/2.

18 = 3/2x

x = 12

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
