Answer:
Solution → (2, -1)
Step-by-step explanation:
Input-output values table for equation (1),
2x + y = 3
x -1 0 1 2
y 5 3 1 -1
Input-output values table for equation (2),
y = x - 3
x -1 0 1 2
y -4 -3 -2 -1
Now plot these points to get the graphs of both the equations.
Common point (2, -1) of both the lines will be the solution of the system of equations.
The answer is median, because the data is skewed and there is an outlier.
Answer:
=0.00015241579
Step-by-step explanation:
Use the formula for geometric sequences:
=

Substitute 1 in for
, -1/3 in for r, and 9 in for n
=(1)(-1/3^9-1)
=(1)(-1/3^8)
=(1)(0.00015241579)
=0.00015241579

Answer:
use math way
Step-by-step explanation:
look up math way
Assume that the dimensions of the room in the plan are a (width ) by b (length),
such that a*b=30.
Since the scale is 1:100, a represents 100a, and b represents 100b.
So the actual dimensions are 100a by 100b.
The area is 100a*100b=a*b*10,000=30*10,000=300,000 (square units)
Answer: 300,000 (square units)
