Answer:
first option
Step-by-step explanation:
solving the inequality
- 13 > - 5x + 2 > - 28 ( subtract 2 from each interval )
- 15 > - 5x > - 30
divide each interval by - 5 , reversing the symbols as a result of dividing by a negative quantity.
3 < x < 6
since the symbol is < then end values will be an open circle with the values between shaded blue, that is the first graph
Answer:
Step-by-step explanation:
I assume your equation to solve is
When we have a product of two factors equal to zero,
The solution is either A = 0 or B = 0.
In this case, this means that we can break the equation into two equations:
Solving the first one, we get:
For the second one, we rewrite it as:
And we see that this equation has two solutions:
Therefore, the three solutions are:
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
The imaginary number <em>i</em> signifies the imaginary part of a complex number. The imaginary part of the number is the coefficient of <em>i</em>. The real part is everything else.
__
In (a +bi), (a) is the real part, and (b) is the imaginary part.
In (-9 +8i), (-9) is the real part and (8) is the imaginary part.
We move all terms to the left:
+31x+32)-((+5)=0
So your answer is 0
