Two equations with infinite solutions would look the exact same. Example:
y=mx+b
y=mx+b
Example 2
y=2x+5
y=2x+5
For an equation with no solution they would have the same slope but different y intercepts. An equation with same slope and same y intercepts would have infinite solutions.

A bicycle is traveling at 70 miles per hour how many feet will it cover in 25 seconds round your answer to the nearest tenth of
gulaghasi [49]

Hey there! I'm happy to help!

We see that the bike travels at 70 miles per hour. There are 5280 feet in one mile, so 70 miles is 369600 (70×5280).

We have 369600 in 1 hour, which is the same as 60 minutes. There are 60 seconds in a minute, so this means that there are 3600 seconds in an hour (60×60).

We have 369600 for 3600 seconds. We want to see how far the bike travels in one second, we simply divide 369600 by 3600.

369600÷3600≈102 2/3.

Now we multiply this by 25 for 25 seconds.

102 2/3×25=2566.7 (rounded to nearest tenth of a foot)

Therefore, in 25 seconds, the bike will have traveled 2566.7 feet.

Have a wonderful day! :D

vladimir2022 [97]

Answer:

D. 1/2

Step-by-step explanation:

Coin tosses are independent.  Past results don't affect future probabilities.  So the probability of getting heads on the fourth toss is still 1/2.

Trig identities how to prove 1- (sin^2x)/(1+cosx)= cosx
balu736 [363]
Both sides aren't equal because 1-sin^2x = cos^2x and cos^2x / 1+cosx can never equal cosx
