Answer:
Simplify the equation
Step-by-step explanation:
4x + 1 + x + -4
= 4x + x + 1 - 4
= 5x + -3
= 5x - 3
Hope this helps
Speed = Distance / time
Distance = Speed x time
In t hours, first plane travels = 600 t miles
In t hours, the second plane travels =150 t miles
After t hours the distance between the two planes is:
(600t+150t)= 750t ( since both travel in opposite directions)
When the distance is 900 miles:
750t= 900
Solve for t:
t= 900/750
t= 1.2 hours
After 1.2 hours.
1.2 x 60 = 72 minutes = 60 +12 = 1 hour and 12 minutes
Since both leave at 10 pm:
10am + 1 hour and 12 minutes : 11:12 am
They will be 900 miles apart at 11:12 am
Each one traveled:
Plane 1:
Distance: Speed x time = 600 mph x 1.2 = 720 miles
Plane 2:
Distance = Speed x time = 150 mph x 1.2 = 180 miles
<span>If a is non empty ordered set, it has a least element.
Let be a non empty subset,we can show that b is well ordered in the same relation. If C is non trivial subset of b, then it is also non trivial subset of a.
But a is well ordered, since c has least element.
Thus b is well ordered.</span>
Answer:
Step-by-step explanation:
I know b is -9 because there's where the line crosses the y intersection.
To find ''m'', we can use 2 different methods. I'm going to use one that follows a formula. First, locate two points in the graph.
