Answer:
The x's cancel so definitely is choice C: 1/9
Step-by-step explanation:
We have root( 1/(x^2) ) * root ((x^2) / 81)
simplifying this we get as follows:
root( 1/(x^2) ) * root ((x^2) / 81)
= 
* 
= ( 1/x ) * (x/9)
the x's cancel
= 1/9
choice C 1/9
For 3, it is an isosceles triangle and it is an acute triangle.
The coordinates of four points on the line are (0,-5), (3,-3), (6,-1) and (9,1)
<h3>How to determine the coordinates?</h3>
The given parameters are given as:
- Slope, m = 2/3
- y-intercept, c = -5
The equation is represented as:
y = mx + c
So, we have:
y = 2/3x -5
When x = 0, we have;
y = 2/3 * 0 -5 = -5
When x = 3, we have;
y = 2/3 * 3 -5 = -3
When x = 6, we have;
y = 2/3 * 6 -5 = -1
When x = 9, we have;
y = 2/3 * 9 -5 = 1
Hence, the coordinates of four points on the line are (0,-5), (3,-3), (6,-1) and (9,1)
