Option D:
is positive product.
Solution:
<em>If the negative sign is in even number of times then the product is positive.</em>
<em>If the negative sign is in odd number of times then the product is negative.</em>
To find which product is positive:
Option A:

Here, number of negative signs = 3
3 is an odd number.
So, the product is negative.
Option B:

Here, number of negative signs = 3
3 is an odd number.
So, the product is negative.
Option C:

Here, number of negative sign = 1
1 is an odd number.
So, the product is negative.
Option D:

Here, number of negative sign = 2
2 is an odd number.
So, the product is positive.
Hence option D is the correct answer.
is positive product.
Answer:
A negative correlation means that there is an inverse relationship between two variables - when one variable decreases, the other increases. The vice versa is a negative correlation too, in which one variable increases and the other decreases.
Step-by-step explanation:
the slope is -12 because y=mx+b and m= slope
Hey sorry if I cant show work but here is the point form:
( 0 , 1 ) and ( -3 , -2 )
Step-by-step explanation:
Use the form (a + b)(a - b) = a^2 - b^2:
(2x^4 + 3x^3)(2x^4 - 3x^3) = 4x^8 - 9x^6.
