Answer: y = (x - 5) ^ 2 + 4
Step-by-step explanation:
Answer:
√19 or 4.36
Step-by-step explanation:
Since one leg is missing, you need to use Pythagorean theorem for this.
The hypotenuse is known so,
c² - a² = b²
c = 10
a = 9
b = ?
10² - 9² = b²
100 - 81 = b²
19 = b²
b = √19

Answer:
Coordinates of B is (3,-4)
Step-by-step explanation:
You multiply -2 by 2 to get -4 and then create the equation 
then you substitue -7 for +7 and add +7 to -4 which gives you 3 (x coordinate of B)
You multiply -1 by 2 to get -2 and then create the equation
then you subtract 2 by -2 which gives you -4 (y coordinate of B)
To check your answer use the midpoint formula 
which will give you the midpoint (-2,-1)
