Answer:
B(4, -5)
Step-by-step explanation:
A(-8, 7)
M(-2, 1)
B(x, y)
x-coordinate:
(-8 + x)/2 = -2
-8 + x = -4
x = 4
y-coordinate:
(7 + y)/2 = 1
7 + y = 2
y = -5
B(4, -5)
Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 32² = 48²
x² + 1024 = 2304 ( subtract 1024 from both sides )
x² = 1280 ( take the square root of both sides )
x = ![\sqrt{1280}](https://tex.z-dn.net/?f=%5Csqrt%7B1280%7D)
= ![\sqrt{256(5)}](https://tex.z-dn.net/?f=%5Csqrt%7B256%285%29%7D)
=
× ![\sqrt{5}](https://tex.z-dn.net/?f=%5Csqrt%7B5%7D)
= 16
→ C
.5 * .5 is .25 just multiply twice since .5 is squared ( .5 is the same as 1/2)
