Its not theres two y for the same x (3)
150 + 15x = 400
(-150) 150 + 15x = 400 (-150)
15x = 250
(/15) 15x = 250 (/15)
x = 16.67

Answer:
A function is a relation in which each input has only one output.
In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.
Answer: 3
Step-by-step explanation: To solve for A we need to get it by itself by doing the inverse of mulitplication, which is, division. 27/9=3, so a=3.
