Answer:
397,800
Step-by-step explanation:
8,840 × 45 = 45 × 8,840 = 397,800
The conclusion is that the system does not have a solution. This is that the equations written do not have an intersection point, they represent parallel lines and, for any x value, one line is always over the other.
In terms of the landscapers charges, it means that the two landscapers have the same hourly rate (the slope of the lines) but different fees..
For example imagine one landscapers charges $0.5 the hour plus a fixed $5 fee
The correspondan equation would be: y = 0.5x + 5
If the other charges $0.5 the hour and a fixed $20 fee. the correspondant equation would be y = 0.5 x + 20
When you try to solve the system you get:
0.5x + 5 = 0.5x + 20
You can remove the 0.5x terms because they appear in the two sides, then
5 = 20.
Which means that the two costs will never be equal.

<span>The standard deviation can be zero if all the data points are the same. Thestandard deviation can be larger than the mean. The range of numbers has to be large for this to occur. One such sample is {0, 0, 1, 15, 20}, where = 7.2 and s 8.6.</span>
The measure of angle D is 39 degrees.
Since it’s an isosceles triangle, the two unmarked angles are equal. Since you know there are 180° in a triangle, subtract 102° from 180° to get 78°. Then, cut that in half since you need to divide it equally among the two remaining angles.
D? Tell me if you got it right
