Answer:
x = -34, y = -17
Step-by-step explanation:
Answer:
(a) dy/dt = 68 - 3.72t
(b) 64.28m/s
Step-by-step explanation:
Given y = 68t - 1.86t²
Average Speed is rate of chance of distance with respect to time. Written as dy/dt
To obtain dy/dt, we differentiate y with respect to t, doing that, we have
dy/dt = 68 - 2(1.86)t
= 68 - 3.72t
(a) dy/dt = 68 - 3.72t
(b) To estimate the speed when t = 1, we substitute t = 1 in dy/dt .
dy/dt at t = 1 is
68 - 3.72(1)
= 68 - 3.72
= 64.28
The speed at t = 1 is 64.28m/s
Both angles equal 73, according to the vertical angle conjecture. To solve for x:
(1+2x)=73
2x=72
x= 36
Answer:The Sleeping bags are 24 dollars and the flashlights are 5 dollars.
Step-by-step explanation:
I personally didn't use elimination, but...
Hopefully this helps you solve it!
Take both groups total and subtract them giving $5 for the flashlights and then take either one of the groups and multiply the number of flashlights by 5, then subtract that from the total from the group you chose. Then, divide the difference by the number of sleeping bags the group you chose bought.

45 seconds is 3/4 of a minuet so after 45 seconds you have done 30/40 push ups after a minute you have done 40/40= one minuet.
