It’s B for sure I hope you have a good day
We have the following function:
N (k):
Where, the indepent variable is k
The dependent variable is N
For the function:
k (n):
the independent variable is n
The dependent variable is k
Thus,
N (12) = 4
k (4) = 12
Answer:
TRUE
option A
We need to write a proportion.
6/2 = (x+2)/x
3 = x² +2x
x² + 2x - 3 =0
(x + 3)(x - 1) = 0
x= -3, x= 1
Because we need to find length x, a length cannot be negative.
So, x = 1.
Answer:

<u>Step 1: Define</u>
(8.1 + 7.4) - 25 ÷ 2.5
<u>Step 2: Evaluate</u>
- (Parenthesis) Add: 15.5 - 25 ÷ 2.5
- Divide: 15.5 - 10
- Subtract: 5.5
3). y = -1/3x + 5
4). y = -1x +5
Slope intercept form: y = mx + b
m = slope
b = y intercept
