Answer:
y>2
Step-by-step explanation:
-4-3y>-10
-3y>-10+4
-3y>-6
y>-6/-3
y>2
(X + 4)(X^2 - 1) = x^3 + 4x^2 - x - 4
Given the equation:

You know that a lab technician finds that a sample of fluid has this pH:

Then, in order to find the hydrogen ion concentration of the fluid, you need to follow these steps:
1. Substitute the pH given in the exercise into the equation:

Multiply both sides by -1:

2. Solve for:

Remember that, by definition:

In this case, you can identify that:

Hence, substituting values and simplifying, you get:

Therefore, the answer is:
Answer:
x = - 3, y = 6
Step-by-step explanation:
For the 2 sides to be equal then the coefficients of the imaginary terms and the real terms must be equal.
Given
- 3 + yi = x + 6i , then
x = - 3 and y = 6
