I don't really speak Spanish but I'll guess that says
How do I solve y = 1 - 2.5
Unless I'm missing something, there's not even any algebra here.
The way we subtract a bigger number from a smaller number is first we subtract the smaller number from the bigger number the regular way, then we prepend a minus sign.
y = 1 - 2.5 = -(2.5 - 1) = -1.5
After I read the equation, I remembered that anything to the power of 1 is itself. so f(x)=2-9
2-9= -7
therefore, f(x)= -7
if x=1, then the f(x) must be Y
<u><em>therefore, your answer should be y= -7</em></u>
Not equivalent expression is validated so I think it’s second one bye
