3 yards . To do d the area you must multiply. We already know its 12 square yards. We need to multiply 4 with 3 because that's what gets is to 12. The width of the rug is 3 yards.
Answer:
Step-by-step explanation:
Percentages? Are you sure that’s not a mistake
(1) 3x+6y-12z=36
(2) x+2y-4z=12
(3) 4x+8y-16z=48
The first equation (1) is the second equation (2) multiplied by 3:
(2) x+2y-4z=12→3(x+2y-4z=12)→3x+6y-12z=36 (1)
The third equation (3) is the second equation (2) multiplied by 4:
(2) x+2y-4z=12→4(x+2y-4z=12)→4x+8y-16z=48 (3)
The equations are linearly dependent, Then the system of equations is dependent, and then consistent too.
The domain of the function are all real numbers greater than 10
<h3>Domain of a function</h3>
Domain are values of the independent variables for which the function exist.
Given the function below;
For the function to exist, then;
-x^2+10x = 0
-x^2 = -10x
x = 10
Hence the domain of the function are all real numbers greater than 10
