Yo sup??
(-1)³=(-1)*(-1)*(-1)
=1*(-1)
=-1
Hope this helps.
Answer:
(-3,4)
Step-by-step explanation:
x + 2y = 5
-3 + (2*4) = 5
-3 + 8 = 5
5 = 5
2x + 3y = 6
(2*-3) + (3*4)=6
-6 + 12 = 6
6 = 6
The slope-intercept form:
m - slope
b - y-intercept
We have m = 2 and b = 3. Substitute:
450 feet below sea level
<em>ascend = move up = add</em>
<em>800 ft below sea level = -800</em>
-800 + 350 = -450
Gradient of line AB = 6/2 = 3.
Gradient of line CD = 10/2 = 5.
Gradient of line AD = 12/8 = 1.5.
