D because there are 8 outcomes
The first relation gives two y-values for any given x-value (except x=6).
y² +x = 6 . . . . . is not a function
Answer:
y=1; x=2
Step-by-step explanation:
Substitution:
x=2y
2x+5y=9
=> if x=2y, plug in the x value into other equation, so
----------------------------------------------------------------------------
2(2y)+5y=9
4y+5y=9
9y=9
y=1
You have the Y value, so now solve for X
-----------------------------------------------------------------------
plug in y value to x=2y
so x=2(1)
x=2
0.5 is a rational number.
The Real Answer is B: Leasing a car for a certain period.
