How do you solve this 10y=40?

y=4

Step-by-step explanation:

u just have to iosalate y by itself so u divide 10 on both sides y=4

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
