Answer:
Step-by-step explanation:
x = time
y = elevation
At x = 0 , y = 0
It takes the submarine 2 hours to make descent of 2100 ft
=> x = 2 , y = - 2100
Slope = ( -2100 - 0)/(2 - 0) = -1050
y - 0 = -1050 ( x -0)
=> y = -1050x
1050x + y = 0
represent the relationship between the submarine's elevation and time.
Y - 1 = m(x - 1) . . . (1)
y = mx - m + 1 . . . (2)
From(2), -m + 1 = 2 => m = 1 - 2 = -1
Substituting for m in (1), we have:
y - 1 = -(x - 1) . . . (3)
Equation of a line in general form is given by ax + by = c
From (3), y - 1 = -x + 1
x + y = 1 + 1
Therefore, required equation is x + y = 2.
Answer:
60
Step-by-step explanation:
If it is an equilateral triangle the sides are equal
24-x = 5x
Add x to each side
24-x+x = 5x+x
24 =6x
Divide by 6
24/6 =6x/6
4 =x
Each side is 5x or 5*4 = 20
Add the 3 equal sides
20+20+20 = 60
The perimeter is 60
