brilliants [131]

Answer:

Step-by-step explanation:

One of the most important things to understand about lines is the definition of slope. Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.

(x+1)(2x-4)(1/x+1)=(x+1)(2x-4)(1-5/2x-4)
ZanzabumX [31]
So you have two parts to eliminate, (x+1) is being multiplied by its reciprocal so you can eliminate that along with the (2x-4).
this brings you to to have 1=(-4/(2x-4)) meaning that if tou multiply both sides by 2x-4 you end up with 2x-4=-4 and can add 4 to both sides, getting 2x=0 or x=0 for your answer. :DDDD

The residents of a city voted on weather to raise property taxes . THe ratio of yes votes was 3 to 5. If there were 4845 no vote
Basile [38]

The total number of votes would be: 7752 total votes.

Here's how you solve it!

For every 3 yes there was 5 no's.

You would but that into a fraction so it would be 3/5

Then you take the number of no votes and multiply.

3/5 x 4845

Then you would get 2907.

4845+ 2907= 7752

4845= no votes

2907= yes votes

7752= total votes

Hope this helps! :3
