Tell whether the equation has one, zero, or infinitely many solutions.
12n + 22 = 10n + 2n + 7

No solution

Step-by-step explanation:

12n + 22 = 10n + 2n + 7

Combine like terms

12n+22=12n+7

Both sides have 12n so they cancel out, meaning whatever you put for n won't matter since 22 ≠ 7

Zero

Step-by-step explanation:

Add the two variables on the right side, the numbers with a letter attached to them. You should have 12. Then subtract 12 from left to right or right from left. It will cancel out both sides.

Subtract 7 from 22, or 22 from seven. You'll get a numerical value, however there are no variables left, therefore your answer is zero

1. 3

hope this ! have a great day.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
