It's important to say that a conjecture, in mathematics, it's a conclusion based on certain evidence and it's supposed to be true. In this case, we have the conjecture: <em>The difference between any two whole numbers is a whole number. </em>

When you have a conjecture, the first thing you have to do is to make sure you know the meaning of each part. For example, you have to know what a whole number is. Basically, whole numbers are all the number from 0 to infinite (not decimal, not fractions), it doesn't include negative numbers.
Once you know what a whole is, then you can analyze the conjecture. Notice that the conjecture states that the difference of two whole numbers is a whole number, but if you subtract 2 - 5 you would get -3 which is an integer but not a whole number.
<h2>Therefore, the difference 2 - 5 can be a counterexample of the conjecture, proving that it's not true for all cases possible.</h2>
Answer:
1/9
Step-by-step explanation:
1/3 ÷ 3
Copy dot flip
1/3 * 1/3
1/9
It takes 10 minutes to ride around your neighborhood. We already know that going around the neighborhood once and your block twice is 15 minutes, so you can get rid of the two blocks and one neighborhood. Then subtract 15 minutes from 55, which is 40. So now we know that it takes 40 minutes to go around the neighborhood 4 times. Devide, and you get that one lap around the neighborhood is 10 minutes. It's kinda hard to explain in words, but maybe the picture will help.
Answer:
y= 3$ + x km * 2$
Step-by-step explanation:
since the callout price is 3$ you are gonna pay at least this much.. and then for every km/mile you will pay 2$.
Answer:
Slope Is 3/2x
Step-by-step explanation:Point Slope Form
Basically
y-y1=m(x-x1)
so
y+1=3/2(x-2)
Slope Intercept Form
y=3/2x-4
