2x - 3 + 3x = -28

= 5x - 3 = -28

= 5x = -28 + 3

= 5x = -25

= x = -25 / 5

= x = 5

In the upcoming election for governor, the most recent poll, based on 900 respondents, predicts that the incumbent will be reele

Dmitriy789 [7]

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

$\frac{45}{100} \times 900$

$= 45 \times 9 = 405$

would not vote for the current governor or indicated that they were undecided.

Determine the discriminant for the quadratic equation 0 = –2x2 + 3. Based on the discriminant value, how many real number soluti

Margarita [4]

we know that

In a quadratic equation of the form $ax^{2}+bx+c=0$ the discriminant is equal to

$(b^{2} -4ac)$

if $(b^{2} -4ac)> 0$ -------> the equation has two real number solutions

if $(b^{2} -4ac)= 0$ -------> the equation has one real number solution

if $(b^{2} -4ac)< 0$ -------> the equation has two complex number solutions

In this problem we have

$-2x^{2} +3=0$

$a=-2\ b=0\ c=3$

substitute in the formula

$(0^{2} -4(-2)(3))=24$

$24 > 0$ ----> the equation has two real number solutions

therefore

<u>the answer is</u>

the equation has two real number solutions
