PLEASE HELP

Mathematics
1 answer:
Butoxors [25]3 years ago
3 0

Step-by-step explanation:

arithmetic operations in functions are simple : you take both expressions and apply the arithmetic operation on them.

in our case : addition.

f(x) = 4x² + 5x - 3

g(x) = 4x³ - 3x² + 5

(f+g)(x) = (4x² + 5x - 3) + (4x³ - 3x² + 5) =

= 4x² + 5x - 3 + 4x³ - 3x² + 5 =

= 4x³ + x² + 5x + 2

so, B should be the right answer (despite all the typos there).

Can someone PLEASE help? i need this done!
iren [92.7K]
It would be .43, rounded. You get this answer by taking all of the 10th graders (14) and looking at how many prefer sporting events (6). Then, you simply form a decimal from 6/14, and that comes out to .428, and .43 rounded up. I hope this helps! :)

0.31 repeating as a fraction
sukhopar [10]
I believe its 31/100! <span>To write 0.3111 as a fraction you have to write 0.3111 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.</span>
