Which product is negative?

−3⋅5⋅(−6)⋅4

−7⋅(−3)⋅(−9)⋅0

−4⋅(−6)⋅(−3)⋅(−5)

−3⋅4⋅(−2)⋅(−7)

-3(4)(-2)(-7) would be the negative answer because it has an odd number of negative numbers.

Hope this helps! ;)

-3⋅4⋅(−2)⋅(−7) is your answer.

Step-by-step explanation:

How you can tell is the first one has two that are negative. If you have an even number of negatives, your answer will be a positive.

That eliminates 1 and 4.

The 3rd one has a 0 so your answer will be 0.

That leaves 4.

-3⋅4⋅(−2)⋅(−7) is your answer.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
