OPTION D

Step-by-step explanation:

THe quadratic formula is shown below:

Given the quadratic equation shown in the image, you have that:

a=1

b=3

c=4

Therefore, when you susbtityte these values into the formula you obtain the following solution:

-4

step-by-step explanation:

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
