For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
According to the statement we have the following equation:
To write the equation of the slope-intersection form we must addto both sides of the equation:
Answer:
The correct option is option C
Answer:
x = -5
Step-by-step explanation:
The equation y = x^2+10x+25 can be factored to (x+5)^2
when (x+5)^2 = 0
x = -5
meaning the equation has a line of symmetry at x = -5
Answer:
The correct option is;
C. She should go back and remeasure all of her specimens again to find the error. If she can't do this, she should eliminate the outlier from the analysis, because this is an error in recording
Step-by-step explanation:
In order to minimize error in measurement, some valuable steps includes;
1) Perform a double check on all measurements to ensure that the measurements recorded are accurate
2) Ensure proper training before taking measurements
3) Measurements should only be taken under controlled conditions
4) Separate the entire population into smaller groups for proper recording
5) Have a second observer double check the records
