Hey there! :)
Since 2 4/5 is greater than 1/4, the answer is negative.
You can just subtract 2 4/5 and 1/4 and add the (-) sign
2 4/5 - 1/4
Change the fractions so they can have a common denominator: 20
2 4/5 = 2 16/20
1/4 = 5/20
2 16/20 - 5/20 = 2 11/20
Add the (-) sign → -2 11/20
Answer ⇒ -2 11/20

Answer:

Step-by-step explanation:
First, we need to look at the # of chips. There are a total of 25, 6 of which are blue.
This means that the chance of getting the first blue chip would be 
As there is no replacement, the total number of chips is 24 and there are only 5 blue left. This gives us the chance of 
Now all we need to do is mulitply these two and then simplify

Answer:
-12x+16=y
Step-by-step explanation:
Subtract 3 from 11: 8-0.5y=6x
Move 0.5y to the right side: 8=6x+0.5y
Move 6x to the left side: -6x+8=0.5y
Divide both sides by 0.5: -12x+16=y
calculating slope formula:
m = (y2-y1)/(x2-x1)
-7 - (-7) = -7 +7 = 0
-24 - (-6) = -24 +6 = -18
m = 0/-18 = 0
next time just look at the y. if they are the same the answer is always 0. if x is same the answer is undefined
