Graph the system below<br> 2x-3y=-18<br> 3x+y=-5

pshichka [43]

Answer:

$x = 3 \frac{(y - 6)}{2} \\ \\ x = \frac{ - 5 - y}{3}$

Step-by-step explanation:

$2x = - 18 + 3y \\ 2x = 3y - 18 \\ x = \frac{3y - 18}{2} \\ x = \frac{3(y - 6)}{2} \\ \\ 3x = - 5 - y \\ x = \frac{ - 5 - y}{3}$

Solve for x in the equation 3 x squared minus 18 x + 5 = 47.

Lana71 [14]

Answer:

first option

Step-by-step explanation:

3x² - 18x + 5 = 47 ( subtract 5 from both sides )

3x² - 18x = 42 ( divide through by 3 )

x² - 6x = 14

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + 9 = 14 + 9

(x - 3)² = 23 ( take square root of both sides )

x - 3 = ± $\sqrt{23}$ ( add 3 to both sides )

x = 3 ± $\sqrt{23}$
