Answer:
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
Answer:
24 5/9
Step-by-step explanation:
convert into improper fraction
13/3*17/3=2211/9
then simplify to
24 5/9
Step-by-step explanation:
Let (x, y) be the coordinates of point B.
(4, 6) => (-2, 4) => (x, y)
We have 2(-2) = 4 + x and 2(4) = 6 + y.
Solving these, we get x = -8 and y = 2.
Hence the coordinates of point B is (-8, 2).
