Answer:
Step-by-step explanation:
Slope of line A = 
= 
= 3
Slope of line B = 
= 
Slope of line C = 
= 
5). Slope of the hypotenuse of the right triangle = 
= 
= 
Since slopes of line C and the hypotenuse are same, right triangle may lie on line C.
6). Slope of the hypotenuse = 
= 3
Therefore, this triangle may lie on the line A.
7). Slope of hypotenuse = 
= 
Given triangle may lie on the line C.
8). Slope of hypotenuse = 
= 
Given triangle may lie on the line B.
9). Slope of hypotenuse = 
= 
Given triangle may lie on the line B.
10). Slope of hypotenuse = 
= 3
Given triangle may lie on the line A.
Answer:
33ft below sea level
Step-by-step explanation:
423-390=33ft
You sometimes need to rewrite a factor because the lead number is not between 1 and 10 as it needs to be in scientific notation. For instance, if we had lead numbers of 2 and 5, as we do in the following problem.
2x10^3 * 5x10^9
Then we get the answer of 10x10^12. We need to adjust this by moving the decimal place and increasing the exponent by 1. The correct answer would be 1x10^13 instead.
In the equation y=mx+b, the variable m represents the slope of the line. Therefore, the equation -5x+2y=10 can be rearranged into 2y=5x+10. Isolate the y to get y=2.5x+5. The slope of the line is 2.5
