SOMEONE SMART PLEASE HELP!! if ax^2+bx+c=0, and a≠0, then x=​

Step-by-step explanation:

Hey there!

Simply, ax²+bx+c = 0 is a standard quadratic equation form.

When any equation is in this form where a ≠ 0;

Hope it helps!

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
