You want to use the slope as y2-y1 over x2-x1. So you subtract 6 from 12 and 5 from negative 3. Hope this helps.
Answer:
f^-1 (x)=(x/2)^(1/3)
Step-by-step explanation:
y=2x^3
x=2y^3
2y^3=x
y^3=x/2
y=(x/2)^(1/3)
You can make a common denominator, then multiple the top by said denominator, then cross it out - because they are the same
Y = mx + b
Plug in
Solution: y = 1/2x + 3
Basically, to find the percent decrease, we first have to find the percent that it is in:
1576n = 1377
n = 1377/1567
(I used a calculator, if you want me to show work, just ask)
0.8787
This is 87.874%
We subtract this by 100%:
100 - 87.874
12.126%
We need to round to the nearest tenth, so:
12.13%
