Answer:
x = 27
Step-by-step explanation:
The angle at any point on a straight line is 180 degrees.
The middle line over there is creating a right angle which is 90 degrees.
This must mean that both sides are 90 degrees.
3x+9 = 90
3x = 81
x = 27
The answer is A. "e" represents a line. When using points represent line, you only need 2. When using points represent plane, you need three but they can't on the same line. And "D" represents a plane.
The average price of such a house is
(97.86/ft²)×(1400 ft²) = 97.86×1400 = 137,004
Answer:
The constant of proportionality is 6
Step-by-step explanation:
Recall the equation for direct variation is 
where 
varies directly with 
and 
is the constant of proportionality. If we take any listed coordinate point, we can determine the value of . I will use (20,120) as an example:
Therefore, the constant of proportionality is 6
