Answer:
x < 
Step-by-step explanation:
Given
- ax + 4b > 9 ( isolate the term in x by subtracting 4b from both sides )
- ax > 9 - 4b ( divide both sides by - a )
Remembering to reverse the inequality symbol when dividing by a negative quantity, thus
x <

Answer:
x = -9 + 11y
Step-by-step explanation:
Simplifying
2x + -22y = -18
Solving
2x + -22y = -18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '22y' to each side of the equation.
2x + -22y + 22y = -18 + 22y
Combine like terms: -22y + 22y = 0
2x + 0 = -18 + 22y
2x = -18 + 22y
Divide each side by '2'.
x = -9 + 11y
Simplifying
x = -9 + 11y
Hope this helps!!
First we are going to reesribir the inaginario number:
i = root (-1)
i = (- 1) ^ (1/2)
Then, we have to
By properties of exponents:
i ^ 3 = i ^ 2 * i
Substituting the value of i:
i ^ 3 = ((- 1) ^ (1/2)) ^ 2 * i
Applying properties of exponents:
i ^ 3 = ((- 1) ^ (1/2)) * ((- 1) ^ (1/2)) * i
i ^ 3 = ((- 1) ^ ((1/2) + (1/2)) * i
i ^ 3 = ((- 1) ^ ((2/2)) * i
i ^ 3 = ((- 1) ^ (1) * i
i ^ 3 = -1 * i
i ^ 3 = - i
