The solution for the x-value in this set is -7≤x
Answer:
All speed from 0 mi/h and 11 mi/h were reached because the initial and final speed was 0 mi/h the speed of 10 mi/hr was reached at least twice in the race.
Step-by-step explanation:
Given,
Total distance covered = 6.2 miles,
Time taken = 34 minutes = hours
( 1 hour = 60 minutes )
Since,
Thus, the speed of the runner =
= 10.9411764706
≈ 11 miles per hour
Thus, the average speed of the runner is 11 miles per hour ( approx )
By MVT,
The speed was exactly 10 mi/hr at least twice in the race.
By intermediate value theorem,
All speed from 0 mi/h and 11 mi/h were reached because the initial and final speed was 0 mi/h the speed of 10 mi/hr was reached at least twice in the race.
its the second option since there are 4 circles and 2 oval things.
hope this helps!! :)
Answer:
$66
Step-by-step explanation:
from the question,
let cost for one purse = X
let cost for one necklace = Y
from the question,
2Y+ 3X= 208.50-------(1)
Y + X = 91.50----------(2)×3
3Y + 3X =274.5--------(3)
subtract equation equation 2 from 3
3Y + 3X = 274.50
2Y + 3X =208.50
Y = 66
cost of one necklace= $66
