Answer:
Intersect: (4 4/7 , 2 6/7)
Step-by-step explanation:
A: slope (m)= (-10-8) / (-9 - 10) = 18/19
Equation: y-8 = 18/19 * (x-10)
18x -19y = 28 (1)
B: slope (m) = (12 - -2) / (0 - 7) = -2
equation: y-12 = -2 *(x - 0)
2x + y = 12
38x + 19y = 228 (2)
(2) + (1): 56x = 256 x = 4 4/7
y = 12 - 2x = 12 - 64/7 = 2 6/7

Step-by-step explanation:
yeah that it is according to my workings
Answer:
He should have done 8^2 + 15^2= x^2 because the hypotenuse is always the longest side and in Pythagorean theorem C represents the longest side
Answer:
Highest Elevation: 14240
Lowest Elevation: -285
Step-by-step explanation:
Given
above sea level
below sea level
Required
Represent both altitudes as an integer
For the Mountain:
Take the sea level as 0 feet



Hence, the integer is 14240
For the Valley:
Take the sea level as 0 feet



Hence, the integer is -285
