2x - 3 + 3x = -28
= 5x - 3 = -28
= 5x = -28 + 3
= 5x = -25
= x = -25 / 5
= x = 5

Answer:
405
Step-by-step explanation:
From the given information, we have 900 respondent.
The poll predicts that the incumbent will be reelected with 55 percent of the votes.
This implies that (100-55=45) percent of the respondents would not vote for the current governor or indicated that they were undecided.
Out of 900 respondents, we have


would not vote for the current governor or indicated that they were undecided.
we know that
In a quadratic equation of the form
the discriminant is equal to

if
-------> the equation has two real number solutions
if
-------> the equation has one real number solution
if
-------> the equation has two complex number solutions
In this problem we have

so

substitute in the formula

----> the equation has two real number solutions
therefore
<u>the answer is</u>
the equation has two real number solutions
