Answer:

x=\sqrt{14.25} -2.5, x=-\sqrt{14.25}-2.5

Step-by-step explanation:

Since moving it to one side can't be factored, I'm going to complete the square.

x^2+5x=8

x^2+5x+6.25=8+6.25

(x+2.5)^2=14.25

x+2.5=\sqrt{14.25}

x=\sqrt{14.25} -2.5, x=-\sqrt{14.25}-2.5

Simplify each side by subtracting the initial fee of 2.50

10=4x

divide by 4 to isolate x

2.5=x

How do u graph linear inequality
amm1812
There are three steps

1 rearrange the equation so "y" is on the left and everything else is on the right

2 plot the "y=" line (make it a solid line for y< or y> and a dashed line for y< or y>)

3 shade above the line for a "greater than" (y> or y>) line under that or below the line for a less than (y< or y< line under it)
