Step-by-step explanation:

\tt{2 {x}^{2}  + 5x - 3 = 0}

⇢ \sf{2 {x}^{2}  + 5x  + ( -  3) = 0}

Here , a = 2 , b = 5 & c = -3 {a is the coefficient of x² , b is the coefficient of x and c is the constant term }

Now ,

\tt{x =  \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} }

⇢ \tt{x =  \frac{ - 5± \sqrt{ {5}^{2} - 4 \times 2 \times ( - 3) } }{2 \times 2} }

⇢ \sf{ x=  \frac{ - 5±7}{4} }

Taking positive ( + ) sign :

⇝\tt{x =  \frac{ - 5 + 7}{4}  =  \frac{1}{2}}

Taking negative ( - ) sign :

⇝\tt{x =  \frac{ - 5 - 7}{4}  =  - 3}

\purple{ \boxed{ \boxed{ \tt{⤑ \: Our \: final \: answer  :  \boxed{ \underline{ \tt{x =  \frac{1}{2} , \:  - 3}}}}}}}

Hope I helped ! ツ

Have a wonderful day / night♡

For a recent year, 38 more Democrats than Republicans represented a country. If the total number of representatives of the count
Fantom [35]

Second question isn't well formatted

Answer:

Number of republicans = 207

Number of democrats = 245

Step-by-step explanation:

Let :

Number of republicans = x

Number of democrats = x + 38

Total number of representatives from the two parties = 452

Tge number of representatives from each party can be calculated thus ;

Number of democrats + number of republicans = total number of representatives

(x + 38) + x = 452

x + 38 + x = 452

2x = 452 - 38

2x = 414

x = 414 / 2

x = 207

Number of republicans = 207

Number of democrats = 207 + 38 = 245

Rom4ik [11]

Answer:

x = 6

Step-by-step explanation:

we can multiply the entire equation by 3 to simplify the numbers

-2x + 27 = 4x - 9

27 = 6x - 9

36 = 6x

x = 6

For geometry:(<br><br> will give brainist to the correct answer!!!
Strike441 [17]

Answer:

y = ⅔x - 5

Step-by-step explanation:

To write the equation, find the slope (m), to enable you write the equation of the line in point-slope form given a point, (-3, -7) that the line passes through.

Since the line is parallel to 2x - 3y = 24,, it would have the same slope (m) value.

Rewrite 2x - 3y = 24 in slope-intercept form.

Thus:

2x - 3y = 24

-3y = -2x + 24

y = ⅔x - 12

The slope of 2x - 3y = 24 is ⅔. Therefore, the line that is parallel to 2x - 3y = 24 is also ⅔.

To write the equation of the line, substitute (a, b) = (-3, -7) and m = ⅔ into y - b = m(x - a)

Thus:

y - (-7) = ⅔(x - (-3))

y + 7 = ⅔(x + 3)

y + 7 = ⅔x + 2

y = ⅔x + 2 - 7

y = ⅔x - 5
