The answer would be 40.2 I'm pretty sure I'm right. I hope I helped!
Y = -2x + 8 <=== this would be ur equation where x is the number of hrs and y is the total distance (in miles) from home
The value of
exists 1061208.
<h3>How to estimate the value of

?</h3>
Let us rewrite
as 
Now utilizing the identity
, we get
a = 100 and b = 2 then substitute the values of a and b then
![(100+2)^3=100^3+2^3+[(3\times100\times2)(100+2)]](https://tex.z-dn.net/?f=%28100%2B2%29%5E3%3D100%5E3%2B2%5E3%2B%5B%283%5Ctimes100%5Ctimes2%29%28100%2B2%29%5D)
= 1000000 + 8 + (600 × 102)
= 1000000 + 8 + 61200
= 1061208
Hence, 
Therefore, the value of
exists 1061208.
