Step-by-step explanation:

For a linear equation to represent a proportion, the y-intercept must be zero. Here, the value of y for x=0 is -5, not 0.

The equation DOES NOT represent a proportional relationship.

Find the median if this set of numbers: 7, 6, 19, 12, 16, 19, 19, 6

tankabanditka [31]

Answer:

Step-by-step explanation:

Order the numbers from smallest to largest, then cross one number off until you have one or two numbers left.

If there is an EVEN number of numbers(like this one): there will be two numbers left, therefore you add those two numbers together, then divide by two.

If there is an ODD number of numbers: there will be one number left, therefore that is your answer!

Hope this helps!

What is the sign of 3x y3xy3, x, y when x>0x>0x, is greater than, 0 and y<0y<0y, is less than, 0?

kaheart [24]

Answer:

B ) Negative

Step-by-step explanation:

Given the expression 3xy

when x>0 and y<0

The value of the expression 3xy will be negative.

This is because the product of a positive and negative number will always be negative.

For illustration,

Let x=5>0 and y=-5<0

3xy=3(5)(-5)=-75

NOTE:

$-X-=+\\-X+=-\\+X+=+$

Montano1993 [528]

Multiply the constants. Multiply the variables according to the rules of exponents.
$(-2q^{4})(-8q^{3}b^{6}) = ((-2)(-8))q^{(4+3)}b^{6}\\\\=16q^{7}b^6}$
