Alison wants to construct the perpendicular bisector of MN¯¯¯¯¯¯¯. What should Alison do for her first step? A.) Place the point
of the compass on point M and draw an arc, using a width for the opening of the compass that is equal to 1/2MN . B.) Place the point of the compass on point M and draw an arc, using a width for the opening of the compass that is greater than 1/2MN. C.) Place the point of the compass on point M and draw an arc, using a width for the opening of the compass that is less than 1/2MN. D.) Use the straightedge to draw a line that intersects MN¯¯¯¯¯¯¯ at a point between M and N.

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:
The transformed equation is:
Step-by-step explanation:
We have to convert the equation in the form
Given equation is:
Adding 8 on both sides
In the given equation
a = x
b= ?
So,
So 3^2 will be added on both sides
Hence,
The transformed equation is:
