Answer:
b
Step-by-step explanation:
centroid
x=(x1+x2+x3)/3=(0+3+0)/3=3/3=1
y=(y1+y2+y3)/3=(0+0-3)/3=-3/3=-1
centroid =(1,-1)
A non-negative root of a number is called Square Root
Answer:
Line 2 and Line 4 are perpendicular
Step-by-step explanation:
Line 2: y=1/5x−3
Line 4: y+1=−5(x+2)
Answer:
DVD: $16
CD: $11
Step-by-step explanation:
These two linear equations can represent the system of equations where x equals the cost of a DVD and y equals the cost of a CD:
3x+4y=92
2x+3y=65
When graphed, the solution is at (16,11).
Therefore, one DVD costs $16 and one CD costs $11.
It's directly proportional, so
m=kw
