<span>Hello : let
A(2,-1) B(8,4)
the slope is : (YB - YA)/(XB -XA)
(4+1)/(8-2) = 5/6</span>
<span>an equation for the line in point-slope form is : y-(-1) =( 5/6)(x-2)
y+1 = (5/6)x -5/3
6y+6 = 5x -10
</span><span>the equation in standard form is : 5x-6y = 16</span>
Answer:
x = 30
Step-by-step explanation:
The two angles add to a right angle which is 90 degrees
30 +2x = 90
Subtract 30 from each side
30 +2x - 30 =90-30
2x= 60
Divide each side by 2
2x/2 = 60/2
x = 30

Answer:
330
Step-by-step explanation:
11
C
4
We use formula n! /((n-r)!r!)
11!/((11-4)!4!)
11!/((7!)(4!))
11x10x9x8x7!/(7!)(4!)
11x10x9x8/(4!)
11x10x72/24
11x10x3
330
Therefore number of ways =330
