What is x?
It is the number of years since purchase. Can this be negative?
NO! Years cannot be negative. So we disregard negative x-axis.
What is y?
It is the value of the computer at that year. A computer starts off with a positive value (y axis) and depreciates to 0 after some years. Can this be negative?
NO! At 0 value, the computer is worth nothing! There is nothing known as <em>negative </em>value. So we disregard negative y-axis.
The graph that Beth will sketch will have to be in the 1st quadrant (positive x-axis & positive y-axis).
ANSWER: Quadrant I only
Median: 5 3/4 ( in a number line from least to greatest, the middle number)
Mode: 6 5/8 ( the number that appears the most [ex: 1,1,2,2,2,3,3 your mode will be 3])
hope this helps
Answer:
x²+6x+9=0
x²+3x+3x+9=0
x(x+3)+3(x+3)=0
(x+3)(x+3)=0
either
x+3=0
x=-3
or
x+3=0
x=-3
Step-by-step explanation:
next method
x²+6x+9=0
x²+2×x×3+3²=0
it is in formula of (x+y)²
(x+3)²=0
x+3=√0
x+3=0
x=-3
So the x intercepts are going to be at the places where y = 0 so you can just read that off and get (-2,0) and (3,0). Hope this helps :)
