Answer:
Step-by-step explanation:
Let the distance be d
<u>Then the time in travel is</u>
- d/60 one way, d/50 on return
<u>The round trip would take 1/2 hours longer if the average speed was 55 mph</u>
- d/60 + d/50 = 2d/55 + 1/2
- d/60 + d/50 - 2d/55 = 1/2
LCM(60,50,55) = 11*12*5*5 = 3300
- 55d/3300 + 66d/3300 - 120d/3300 = 1/2
- d/3300= 1/2
- d = 1650 miles
Hello
<span>an equation for the line in point-slope form and general form is :
y = ax+b a : </span>slope ; the <span>Passing through (x' ; y')
</span>y' = ax'+b
y-y' =a(x-x') and : x' =8 y' = -4
calculate a :
let : y = ax+b .....(D)
....(D') y = (1/5)x+4
.(D) perpendicular to(D') : slope (D) × slope (D') = -1
slope (D') = 1/5
slop(D)×(1/5) = -1
slope (D) = -5
equation for the line : y-y' =a(x-x')
y+4 =(-5) (x-8)
Answer:
I would say 50%
Step-by-step explanation:
For this case, what you must have is the following:
You must multiply each row for each column.
Thus you get the ternimos of the matrix AB.
