1) domain: x cannot be -1/3, 0
2) domain: m cannot be 4/3, -7/2
3) domain: m cannot be 3
6.4$
Solution:
Divide 40 and 100(there must always be 100 when solving percentage) then it would be equal to 0.4
after it Multiply it to 16
so we get 6.4.
<span>y=-4/x+1 is ambiguous, since it's not immediately clear whether you meant
-4
y = -4/x + 1 or y = ---------
x+1
I'm going to assume that the latter is what you meant.
1. Interchange x and y, obtaining:
-4
x = --------
y+1
2. Solve this for y, obtaining y+1 = -4/x, or xy + x = -4, or
-x - 4
xy = -x-4, or y = ---------
x
-1 -1 4
3. Replace y with f (x): f (x) = -1 - -----
x
This last result has the correct form.</span>
I believe A is the answer!
Answer:
7i
Step-by-step explanation:
We know that i = √-1
Then solving the given:
- √-49 = √49×(-1) = √49 × √-1 = 7×√-1 = 7i
So the answer is:
