Are you sure your question starts with Why?
I believe it should start with what, if so then Z is the 100's
For your info: N is the thousand's, Z the hundred's, Q tenth & R the unit
Answer:
The system of equations has infinite solutions. True for all y and x.
Given equations:
x + 4y = 0
20y = - 5x
Make x the subject for equation 1:
x + 4y = 0
x = -4y
Plug x as -4y in second equation:
20y = - 5x
20y = - 5(-4y)
20y = 20y
0 = 0
L.H.S = R.H.S
True for all y.
Therefore true for all x.
Answer:
x=-1
Step-by-step explanation:
y=-4x+5
y=x+10
------------
-4x+5=x+10
-4x-x+5=10
-5x=10-5
-5x=5
x=5/-5
x=-1
We can set this geometric sequence up as so:
y = 50,000(0.90)^(x - 1)
The value of the car is represented by y, and the year is represented by x.
