Answer:
-6
Step-by-step explanation:
The notation a23 refers to the element in row 2, column 3. That element is -6.
True
A triangle that has an angle greater than 90 degrees, it is not a right triangle
How to solve: 20^2+5^2=x^2, then you take the square root, therefore x=20.62
The slope of the line is 50. You can try looking at the equation, which is
y=50x+500
500 is your y-intercept, and is where the cost starts.
50 is your slope, since the cost goes up by $50 every time.
x is how many hours, which determines how many $50s there are.
I hope this helps. All in all, the slope is 50.
1, X = 6
2, X = 13
3, X = 9
