F(x)=6(2-x), find f(-9)

66

Step-by-step explanation:

To find f(-9) we can plug -9 in for x:

f(x)=6(2-x)

f(-9)=6[2-(-9)]

f(-9)=6(2+9)

f(-9)=6(11)

f(-9)=66

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

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
