Answer:
I think I don't understand the question
The 2nd quadrant
.........
Answer:
(25,-26)
Step-by-step explanation:
difference between the two points in x and y coordinates are
x = 10 - (-5) =15, y = -9 - 8 = -17,
so to get to the other endpoint you need to add another
x = 15 and y = -17 to the midpoint, (10,-9).
10+15 = 25 for x and -9 - 17 is -26 for y.
Answer:
<h3>
y = - (x - 5)² + 7</h3>
Step-by-step explanation:
y = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)
So the equation of the parabola with vertex (5, 7):
y = a(x - 5)² + 7
The parabola passes through point (2, -2) so if x=2 then y=-2
- 2 = a(2 - 5)² + 7
- 2 -7 = a(-3)² + 7 -7
- 9 = 9a
a = - 1
So, the equation written in vertex form of a parabola with a vertex of (5, 7) that passes through (2, -2):
<u> y = - 1(x - 5)² + 7</u>
