What is f(3) if f(x) = –4x + 1? a. –42 b. –11 c. 1/2 d. 11

B. -11

Step-by-step explanation:

f(x) = –4x + 1

f(3) = -4(3) + 1

f(3) = -12 + 1

f(3) = -11

it would be 6xy and -16xy.

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
