Answer:
The answer to your question is x-axis, y-axis
Step-by-step explanation:
To answer this question just remember the equation of the slope
m = 
Then:
If the numerator is zero, the line is parallel to the x-axis and the slope will be zero.
If the denominator is zero, the line is parallel to the y-axis and the slope will be undefined.
To solve this problem you use the "Triangle Inequality Theorem" it states that: any side of a triangle is always shorter than the sum of the other two sides.
Using this theorem we check each side
5+7=12: this is greater than the other side which is 11, so this works
11+7= 18: this is greater than the other side which is 5, so this works
5 + 11= 16: this is greater that the other side which is 7, so this works
If c is the hypotenuse, we have

If instead b is the hypothenuse, you have

Her error in terms of inches was 2 inches while her percent error was 4.166%
Step-by-step explanation:
Step 1; From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.
We convert the feet into inches because 12 inches are equal to a feet.
4 feet = 4 × 12 inches = 48 inches
4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches
Error in terms of inches = 50 inches - 48 inches = 2 inches.
Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.
% error = (difference in values / actual value) × 100
Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%.
