Answer:
20
Step-by-step explanation:
f(x) = 30
30 = 1.8x -5.4
35.4 = 1.8x
x = 35.4/1.8
x = 19.666
I think the answer is Rectangle
We don't need to graph the line. All we have to do is use our slope formula.

Answer: A then 0.700 .7 .70
Step-by-step explanation:
Answer:
B) 16 . . . . the value of Z
Step-by-step explanation:
The problem statement tells us that ...
... x = y +12
... z = y - 8
Then x - z = (y +12) -(y -8) = 20.
In ratio units, we have ...
... x:z = 9:4
The difference of these in ratio units is 9-4 = 5, so each ratio unit must stand for 20/5 = 4 units of X, Y, or Z. Hence ...
... Z = 4·4
... Z = 16
_____
<em>Check by finding the other values</em>
... X = 9·4 = 36
... Y = X -12 = 24 = Z +8 . . . . yes
