There were 70
runners to start a race. In the first half of the race,
1/5
of them dropped out. In the second half of the race,
4/7
of the remaining runners dropped out. How many runners finished the race?

Answers

Answer 1

Answer: Hey there! So,to do this, I would recommend making the fractions into decimals. 1/5 is equal to 0.2 so you multiply that times 70 runners . This equals 14 runners who dropped out. Subtract those who dropped out from the total and now you have 56 runners left. 4/7 as a decimal is about 0.575. Times that by 56 and you get another 32 who dropped out. You're now down to only 24 runners who finished the race.

The end behavior of the following function is that it starts high and ends high.

How do we make a graph of a function?

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

Suppose the considered function whose graph is function of x

Then the values of 'x' (also called input variable, or independent variable) are usually plotted on the horizontal axis, and output values function of x are plotted on the vertical axis.

We have been given a function of x as $2x^4 +x^3$

The graph of the given function starts high and ends high.

The function touches the origin in the middle of the line.

Hence, the end behavior of the following function is that it starts high and ends high.

Can someone please tell me if i am right?

Answers

Second one is correct, that is an identity.

Third one is a contradiction:
6x - 15 = 3 * (2x - 6) ------> 6x - 15 = 6x - 18

Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.
