Answer:
Elena won the race.
Step-by-step explanation:
If you calculate it, Lin runs a mile every 9 minutes.
9 times 7.5= 67.5 which is 1 hour, 7 minutes and 30 seconds. While it took only an hour for Elena to run 7.5 miles.
Which means Elena's speed was faster and got her to the finish line first.
Answer:
Step-by-step explanation:
Prove that for any natural number 3^(n+4)-3n is divisible by 16.
(I'm going to assume that you mean 3^(n+4)-3^n.)
1. We can break up 3^(n+4)-3n into 3^n * 3^4-3^n (by the rule a^b*a^c = a^b+c).
2. Solve to get 3^n * 81 - 3^n
3. Factor out the 3^n, and you'll get 3^n(81-1), and simplify: 3^n(80)
You may notice that 80 is divisible by 16.
4. Rewrite what we got from the last step as: 3^n*5(16).
Hope this helped you!
Answer:
true
Step-by-step explanation:
well youll have to multiply both sides by v to get m alone. and youre left with DxV=M
-6x + 5 > -1
-6x > -1 - 5
-6x > -6
x < -6/-6
x < 1 <===
The relationship is x=4.4 when y is 1.7
Step-by-step explanation:
The functions are :
Because they are linear functions, a relationship can be identified if you graph the functions using a graph tool and visualize their point of intersection to see the values of x and y at that point.These values will satisfy both the functions to show that the two functions have a relationship.
