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

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
