Answer:
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola.
Step-by-step explanation:
Answer:
Two right angles = 180 degrees
Step-by-step explanation:
A right angle = 90 degrees
The sum of the interior angles of a triangle = 180 degrees
Two right angles (2 * 90) = 180
180 = 180
Therefore, the sum of the interior angles of any triangle is equal to two right angles.

Answer:
Step-by-step explanation:
If B lies between A and C on a line segment, then ...
AB +BC = AC
(2x -17) +(x +1) = 14
3x = 30 . . . . . . . . . . . . . add 16, collect terms
x = 10 . . . . . . . . . . . divide by 3
AB = 2(10)-17 = 3
BC = 10+1 = 11
Answer:
slope = 
Step-by-step explanation:
calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (2, - 9 ) and (x₂, y₂ ) = (12, 6 )
m = 
= 
=
