F(x)=x−7
g(x)=4x^3

what is f(x)+g(x)?

f(x)+g(x)=x+x
f(x)+g(x)=4x^3+x−7
f(x)+g(x)=−4x^3−x+7
f(x)+g(x)=4x^3+x

f(x)+g(x)=4x^3+x−7

Step-by-step explanation:

To find f(x) + g(x) add the expressions together by combining like terms. Recall like terms are terms with the same base and exponent.

f(x) + g(x) = x - 7 + 4x^3

f(x) + g(x) = 4x^3 + x -7

step-by-step explanation:

pleaze mark brainliest!

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
