Sebastian solved the radical equation y + 1 = but did not check his solution. (y + 1)2 = y2 + 2y + 1 = –2y – 3 y2 + 4y + 4 = 0 (

Softa [21]

Answer:

There are no true solutions to the equation.

Step-by-step explanation:

The correct equation is

$y+1=\sqrt{-2y-3}$

Solve for y

squared both sides

$(y+1)^2=(-2y-3)$

$(y^2+2y+1)=(-2y-3)$

$y^2+2y+1+2y+3=0$

$y^2+4y+4=0$

$(y+2)(y+2)=0$

$y=-2$

Verify

substitute the value of y in the original expression

$-2+1=\sqrt{-2(-2)-3}$

$-1=1$ ----> is not true

therefore

There are no true solutions to the equation.

To become a member at a local nature preserve, applicants must pay an initiation fee of $100 plus their yearly membership dues ,

Natalija [7]

The points are (2,150), (4,200).

The slope of the line joining the points is,

$\begin{gathered} m=\frac{200-150}{4-2} \\ =25 \end{gathered}$

Thus, the slope represents the increse in cost per year of membership.
