Between which two ordered pairs does the graph of f(x)=1/2x^2+x-9 cross the negative x-axis?

(-6,0) and (-5,0)
(-4,0) and (-3,0)
(-3,0) and (-2,0)
(-2,0) and (-1,0)

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

8+10

step-by-step explanation:
