Answer:
-8b+36 is the answer.
Step-by-step explanation:
=8(-b+4)
Opening brackets to simplify
=8✖️(-b)+8✖️4
=-8b+36 is the answer.

Answer:
Total Distance = 2 miles
Step-by-step explanation:
We know D = RT where
D is distance
R is rate (speed)
T is time
First Leg:
Rate = x mph
Time = 20/60 = 1/3 hour
Hence, D = RT, Distance = x * 1/3 = x/3 miles
Second Leg:
Rate = x - 1
Time = 30/60 = 1/2 hour
Distance = (x - 1) * 1/2 = (x-1)/2
Total distance is the sum of both the legs, hence,
Total distance =
miles
Since both the distance are equal we can equate and solve:
![\frac{x}{3}=\frac{x-1}{2}\\2x=3x-3\\x=3](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B3%7D%3D%5Cfrac%7Bx-1%7D%7B2%7D%5C%5C2x%3D3x-3%5C%5Cx%3D3)
Plugging this x = 3 into the total distance expression, we get:
![\frac{5x-3}{6}\\\frac{5(3)-3}{6}\\=2](https://tex.z-dn.net/?f=%5Cfrac%7B5x-3%7D%7B6%7D%5C%5C%5Cfrac%7B5%283%29-3%7D%7B6%7D%5C%5C%3D2)
Total distance, 2 miles
Answer:
A) -2/5
Step-by-step explanation:
Note that for a slope, the slope of the line is found by using the equation:
slope = (rise/run).
In this case, find two points. For example, i will use:
(0, 2) & (5, 0). (x = 0, y = 2) ; (x = 5, y = 0)
Note that "rise" = y, and "run" = x. Plug in the corresponding numbers for the corresponding points.
(2 - 0)/(0 - 5) = slope
Simplify
(2)/(-5) = slope
-(2/5) is your answer.
Note that it does not matter where the negative sign is placed.
