first, consider that 25 = 5^2, and -25 = -1*25 = -1*5^2.
Then, you can write:
because i = √-1.
Hence, the answer is 5i
The first number in an ordered pair tells you the distance to move right or left from the origin.

Answer:
Correct option is C
Step-by-step explanation:
First, find the equation of the boundary line. This line passes through the points (0,-3) and (-2,1). Then it has equation
In the attached diagram this boundary line is solid, then the sign of the inequality should be with "or equal to" notion (≤ or ≥). Thus, options A and B are false.
The line divides the coordinate plane into two parts and you have to determine which part to choose. The origin does not lie in the shaded region, then its coordinates cannot satisfy the inequality. Check options C and D.
- origin does not satisfy (option C is correct);
- origin satisfies (option D is false).
Answer:
The dependent variable is A
The independent variable is w
Step-by-step explanation:
Given
Required
Identify the variables
In
The value of w is independent of the value of A.
In other words:
A derive its own value from w; by multiplying 25 and w.
Take for instance:
The value of A would be:
Hence:
The dependent variable is A
The independent variable is w
