Answer:
40% Increase
Step-by-step explanation:
![Formula:\frac{Final Price-Startingprice}{Original price} *100](https://tex.z-dn.net/?f=Formula%3A%5Cfrac%7BFinal%20Price-Startingprice%7D%7BOriginal%20price%7D%20%2A100)
1.75-1.25=0.50
0.50/1.25x100=40%
Hence, the percent increase in 40%
<u>Check Answer:</u>
$1.25 x .40=0.50
1.25+0.50=1.75
Hence, 40% is the correct Answer.
You look at where the line strikes <em>through </em>the y axis! That ordered pair is going to be your y intercept. =)
A solid dot on the graph of an inequality indicates that the number is contained within the inequality, so yo should use
![\leq](https://tex.z-dn.net/?f=%20%5Cleq%20)
or
![\geq](https://tex.z-dn.net/?f=%20%5Cgeq%20)
to represent that situation, whereas a white dot indicates that the number is not contained within the inequality.
Our graph is telling us that
![x](https://tex.z-dn.net/?f=x)
is greater or equal than -1, and also
![x](https://tex.z-dn.net/?f=x)
is less than 3. So our inequality will be:
I think that the answer would be -30
