Plz help :( what is n – 10 + 2n + 5

n-10+2n-5

to me it look like it equal 3n-5

Step-by-step explanation

step one:

add n+2n which equal to 3n

step 2:

-10+5

you add 5 do -10 which equal to -5

and when u put them together the answer will be

3n-5

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
