Answer: The solutions are x = 3+sqrt(2), and x = 3-sqrt(2). The quadratic equation has two solutions because it has a positive discriminant.

Step-by-step explanation:

Using the quadratic formula, we have: 6+-sqrt(8)/2, which become 3+-sqrt(2).

What is the equation, in slope-intercept form, of the line that is perpendicular to the line
nexus9112 [7]

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(-3/2) = -1......( perpendicular to a line with a slope of -3/2)
a = 2/3        y=(2/3)x+b
the line that passes through (-2, -2) : -2 = (2/3)(-2)+b
b = -2/3
<span> the equation is :  y  = (2/3)x-2/3</span></span>

Solve for x 2x/3 +1 =3
Bess [88]

Answer:

x=3

Step-by-step explanation:

Hello,

The first thing you do is set up your equation, and we are solving for x so we are going to get x by itself on one side of the = sign.

       2x/3+1=3        First thing: subtract 1 from BOTH sides.

               -1  -1

----------------------

          2x/3=2       Multipliy by 3 on both sides

              *3 *3

-----------------------

            2x=6         Divide by 2 on both sides

             /2 /2

-----------------------

           x=3

I hope this helped you!!!

What is the difference <br> A <br> B<br> C<br> D
aksik [14]

Answer:

D. \frac{x-1}{x^2+3x+2}}

Step-by-step explanation:

The given expression is;

\frac{x}{x^2+3x+2}-\frac{1}{(x+2)(x+1)}

This is the same as;

\frac{x}{(x+2)(x+1)}-\frac{1}{(x+2)(x+1)}

The denominators are the same.

Subtract the numerators and write one denominator;

\frac{x-1}{(x+2)(x+1)}}

Rewrite to get;

\frac{x-1}{x^2+3x+2}}
