If xy < zy < 0, is y positive? x < z x is negative
statement (1) alone is sufficient, but statement (2) alone is not sufficient to answer the question asked
statement (2) alone is sufficient, but statement (1) alone is not sufficient to answer the question asked
both statements (1) and (2) together are sufficient to answer the question asked; but neither statement alone is sufficient

Both statements (1) and (2) TOGETHER are sufficient to answer the question asked

Step-by-step explanation:

Given statement 1 :

xy < zy < 0,

The product of two numbers are negative if either of the numbers are negative.

∵ if xy < 0 ⇒ Case 1 : x > 0 and y < 0

Case 2 : x < 0 and y > 0,

Thus, Statement is not sufficient to prove y is positive,

Now, Statement 2 :

x < z, x is negative,

That is, x < 0

Combining statements (1) and (2),

We get,

xy < 0, x < 0,

⇒ y > 0

That is, y is positive.

Hence, Both statements (1) and (2) TOGETHER are sufficient to answer the question asked

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

my answer is$ 12

step-by-step explanation:

because 15 -2=12
