Given:
Triangle Point coordinates or vertices:
A(16,0)
B(9,2)
C(2,0)
Required:
Side with slope -2/7
Solution:
To know which side has the slope required, we need to calculate the slope of each paired point by the two-point slope formula:
m = (y2-y1)/(x2-x1)
We first try points A and B.
m1 = (2-0)/(9-16)
m1 = -2/7
Thus, the side with the slope -2/7 is side AB.

Answer:
x = 1/3 or -2
Step-by-step explanation:
2x^2 + 7x - 2 = - x^2 + 2x
3x^2 + 5x - 2 = 0 (use factoring)
(3x − 1)(x + 2) = 0
3x - 1 = 0 OR x + 2 = 0
3x = 1 x = - 2
x = 1/3

X is equal to 440
440/8=55
Answer:
The answer to the question is
1.5 hours that is;
When the distance between them is more then 135 miles is after 1.5 hours and they will lose radio contact at 3:30 p.m.
Step-by-step explanation:
We note that
The speed of the military convoy headed north =50 mph
The speed of the convoy headed south = 40 mph
Let t be the time taken for the two convoys to be 135 miles apart
The time taken for the two convoys to be 135 miles apart is given by
50×t miles+ 40×t miles= 135 miles
That is 90×t miles = 135 miles
t = 135/90 = 1.5 hrs
