What are the points for -3x+6y+5=-7
Novay_Z [31]
-3x + 6y + 5 = -7
<u>                -5    -5</u>
      -3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
<u>6y</u> = <u>-12 + 3x</u>
 6           6
  y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
-3x - 12 + 3x = -12
-3x + 3x - 12 = -12
0x - 12 = -12
<u>     +12   +12</u>
       <u>0x</u> = <u>0</u>
        0     0
         x = 0
-3(0) + 6y = -12
0 + 6y = -12
<u>+0           +0</u>
      <u>6y</u> = <u>-12</u>
       6       6
        y = -2
  (x, y) = (0, -2)

Find the exact solution of x <br> 3x^2+7=28<br> A.+√7<br> B.7<br> C.+7<br> D.-7
yulyashka [42]

Answer:

x = ± \sqrt{7}

Step-by-step explanation:

3x² + 7 = 28 ( subtract 7 from both sides )

3x² = 21 ( divide both sides by 3 )

x² = 7 ( take square root of both sides )

x = ± \sqrt{7}

that is x = - \sqrt{7} , x = \sqrt{7}
