Answer: The required inequality would be ![\dfrac{d}{55}+3.5\leq 8](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7B55%7D%2B3.5%5Cleq%208)
Step-by-step explanation:
Since we have given that
Time should be no more than 8 hours in one day.
He already drive for = 3.5 hours
Average rate of driving = 55 miles per hour
So, distance would be
![d=speed\times time\\\\d=55\times t\\\\\dfrac{d}{55}=t](https://tex.z-dn.net/?f=d%3Dspeed%5Ctimes%20time%5C%5C%5C%5Cd%3D55%5Ctimes%20t%5C%5C%5C%5C%5Cdfrac%7Bd%7D%7B55%7D%3Dt)
So, the required inequality would be
![\dfrac{d}{55}+3.5\leq 8](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7B55%7D%2B3.5%5Cleq%208)

Answer:
-3 1/2
Step-by-step explanation:
We have to find the distance between x and z along the y-axis.
This will be: 5 - -6 = 11 units
1/5 of 11 = 1/5 × 11
= 11/5
= 2 1/5
Now add 2.5 to -6
2 1/2 + -6 = -3 1/2
The value of y = -3 1/2
First change the first equation in to slope-intercept form
y=mx+b<-----slope intercept form
m=slope
b=y-intercept
4y=-x+8
y=1/4x+2<----final slope-intercept form
now, you know there is a point that is (0,2), the y-intercept, so now you calculate the slope.
y2-y2/x2-x1<------slope formula
3-2/0-3
1/-3
-1/3<---slope
so your final equation is
y=(-1/3)x+2
hope this helps! :)
