Step-by-step explanation:
a) gradient= y2-y1/x2-x1
gradient of AB:
gradient=-4-1/2-3
=-5/-1
=5
gradient of BC:
=-5+4/7-2
=-1/5
b) as the priduct of both gradient is -1 ,both lines are perpendicular.
c) as we have seen lines are perpendicular so it is a right angled triangle.
Not sure what your asking but:
0.000675 is equivalent to 6.75x10^-4
hope this helps
Answer:
Step-by-step explanation:
y + 4 = -8(x - 2)
I dont know the statements that u have but maybe I can guess one...or two
slope = -8
points used were : (2,-4)
y + 4 = -8(x - 2)
y + 4 = -8x + 16
y = -8x + 16 - 4
y = -8x + 12 ............slope intercept form
8x + y = 12 .......standard form
x intercept = (3/2,0)
y intercept = (0,12)
any of that answer ur question ?
Answer:
k= 20
Step-by-step explanation:
You start with this equation:
k-16=4
Add 16 on both sides.
k=4+16
Simply.
k=20
If you want to check your answer, you can just plug 20 into where k is back into the equation:)
Hope this helps!
