first, consider that 25 = 5^2, and -25 = -1*25 = -1*5^2.
Then, you can write:
![\sqrt[]{-25}=\sqrt[]{(-1)(25)}=\sqrt[]{(-1)(5^2)}=5\sqrt[]{-1}=5i](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B-25%7D%3D%5Csqrt%5B%5D%7B%28-1%29%2825%29%7D%3D%5Csqrt%5B%5D%7B%28-1%29%285%5E2%29%7D%3D5%5Csqrt%5B%5D%7B-1%7D%3D5i)
because i = √-1.
Hence, the answer is 5i
Answer:
I can't submit a photo but here:
x = 4, y = 16
(4,16)
You can choose whichever format
Step-by-step explanation:
We have x given to us already. Since we know the value of x, we can input the value into the other equation to solve for y
Solve:
Substitute 4 for x:
- y = 2x + 8
- y = 2(4) + 8
- y = 8 + 8
- y = 16
Our solution is x = 4 and y = 16, or (4,16)

Answer:
Yes this statement is true because 0/3 is 0
Answer:
slope is -1/2 and y- intercept is 1/3
Step-by-step explanation:
use y=mx+b
m=slope
b= y-intercept
rearrange your equation
y=1/3-1/2x
y=-1/2x+1/3
