X = 7
Is a vertical line that passes through (7,-3).
Answer:
4:1 (I think)
Step-by-step explanation:
Let's write some equations first:
For both prices increasing by 20:

then we can use cross multiplication
2x+40=5y+100
For both prices decreasing by 5:

same here:
5y-25=x-5
Using substitution for 5y, we get: 5y=x+20
2x+40=5y+100
2x+40=x+20+100
x=80
plugging this in to the second equation:
5y-25=x-5
5y-25=80-5
5y-25=75
5y=100
y=20
therefore we get x:y=80:20
4:1
In 2005, 23 is in the second deviation
19 22 25 28 31 33 35
In 1965, 23 is in the third deviation.
12 14 16 18 20 22 24
<span>By the way, 13.5% range from 22 to 25 in 2005, while 2.1% range from 22 to 24 in 1965</span>
