Ok so the formula for point-slope is:
m=slope
y1 = y point that's given
x1 = x point that's given
The problem says "use the point (-1,-4)"
so we will put it into our equation.
(-1,-4)
-1 is our x, and -4 is our y, now we can put it into the equation.
Now we need to find the slope using:
y2=4
x2=3
y1=-4
x1=-1
m=2
So the answer is..
The system:
- 12 c + 3 d = 6
- 3 c + 6 d = - 9
----------------------
The 1st equation:
- 12 c = - 3 d + 6 / * ( - 1) ( multiple both sides by -1 )
12 c = 3 d - 6 / : 12 ( divide both sides by 12 )
c = d / 4 - 1/2
Answer:
C ) c = 1/4 d - 1/2
Hello!
Since the shape has 6 points it is a hexagon
The sum of the angles in a hexagon add to 720
You add all the angles you know
102 + 133 + 117 + 170 + 90 = 612
Subtract this from 720 to find b
720 - 612 = 108
The answer is B) 108°
Hope this helps!
