Answer:
Step-by-step explanation:
Rewrite this as

Knowing that i-squared = -1:

Both i-squared and 100 are perfect squares, so this simplifies to
±10i
Answer:
17 and 44
Step-by-step explanation:
Let S = smaller number, then L = the larger = 3S - 7
The sum = 3S - 7 + S = 4S - 7 = 61
4S = 68
S = 17 and L = 44
Solution
We have the following system of equations:
y=2x+1 (1)
-4x+2y=2 (2)
We can replace the first equation in the second one and we got:
-4x + 2*(2x+1) = 2
And solving for x we got:
-4x +4x +2= 2
2=2
Then the system have infinite solutions
