Y/X=? Basically saying that 72 divided by 3 is what

y = kx

Replace y and x to solve for k:

72 = 3k

Divide both sides by 3:

k = 24

Now replace k with 24:

y = 24x

Are these triangles similar? (worth 25 points)

zloy xaker [14]

Find angleK:

Angle k = 180-45-85 = 50

Both triangles have an angle equal to 85 and 45, which makes the 3rd angle in both triangles equal to 50

Because all three angles are the same the triangles are similar.

If p is the hypothesis of a conditional statement and q is the conclusion, which is represented by ~p → ~q?

AfilCa [17]

Conditional statement is a statement with a hypotesis and a conclusion:

If $\text{ \underline{ hypothesis } } p$ , then $\text{ \underline { conclusion } } q$ or mathematically $p\rightarrow q$ .

Converse statement of $p\rightarrow q$ is statement $q\rightarrow p$ .

If you negate (that means stick a "not" in front of) both the hypothesis and conclusion, you get the inverse: $\neg p\rightarrow \neg q$ .

Finally, if you negate everything and flip p and q (taking the inverse of the converse) then you get the contrapositive: $\neg q\rightarrow \neg p$ .

Then,

Answer: the correct choice is D (the inverse of the original conditional statement).
