Which graph shows the solution set of x^2+9x-22/x+4=> 0?

Let's solve your inequality step-by-step.

x2+9x−22/x+4  >0

Let's find the critical points of the inequality.

x2+9x−22/x+4  =0

x2+9x−22=0(Multiply both sides by x+4)

(x−2)(x+11)=0(Factor left side of equation)

x−2=0 or x+11=0(Set factors equal to 0)

x=2 or x=−11

Check possible critical points.

x=2(Works in original equation)

x=−11(Works in original equation)

Critical points:

x=2 or x=−11(Makes both sides equal)

x=−4(Makes left denominator equal to 0)

Check intervals in between critical points. (Test values in the intervals to see if they work.)

x<−11(Doesn't work in original inequality)

−11<x<−4(Works in original inequality)

−4<x<2(Doesn't work in original inequality)

x>2(Works in original inequality)

−11<x<−4 or x>2~

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

6e14 is the answer.
