Y= (x-2)² + 5. We can write it as : y-5 = (x-2)². The general equation of a quadratic function is :
(y-k) = a(x-h)², where h and k are the vertex of the parabola and a, the coefficient which determines whether the parabola opens upward or downward.
So, y-5 = (x-2)²
Having said that we can say that the VERTEX( 2,5) and since a=1 (a>0) the parabola is open upward OR it passes by a MINIMUM (Then the vertex is minimum)
The domain (x- value) is all Real { x|x = -∞ to x=+∞}
The Range (y-value) is all y ≥ 5
Ok so I have a way you can find the answers. Go look online and use Socratic
Answer:
l think 10
Step-by-step explanation:
a=?
b=20
c=30
30-20=10
The answer would be 48. Since UW is an angle bisector that would mean the angle was split in half evenly. Since the angles are now even, VUW = WUT. You can put the two equations equal to each other (4x + 6) = (6x - 10) after solving you would find that x = 8. Take that 8 and substitute it in the equation ( 6(8) - 10 ) and solve it.
Answer: I don't know about the formula, but consider the logic below.
Step-by-step explanation:
Martina = 12
Joey = 0
12 x 3 = 36
36 - 3 = 33
If Joey was 21, Martina would be 33.
