Answer:
42+18=6(7+3)
Step-by-step explanation:
6x7=42 and 6x3=18
Slope of perpendicular is -1/3.
Then equation is
y-5=(-1/3)(x+9)
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
