Solve equation by using the quadratic formula. 15 x squared + 13 x = 0 a. x = negative StartFraction 13 Over 15 EndFraction, 0 c. x = StartFraction 13 Over 15 EndFraction, 0 b. x = 0 d. x = plus-or-minus StartFraction 13 Over 15 EndFraction

honestly bro aint no one got time to answer these dumb question just do it p***y

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
