Hi!
So, we need to find the inverse of the function f(x) = 15x - 7.
To start, we must turn the f(x) into a y.
y = 15x - 7.
Now, we swap all the x variables for the y variables, and swap all the y variables for the x variables!
x = 15y - 7.
Now, we simply must work on isolating y. Assuming you know how to isolate a variable, we must do the steps below -
x = 15y - 7.
Add 7 on both sides.
x + 7 = 15y - 7 + 7.
We cannot add x and 7, as they are not like terms. So, they will remain like that, while the 7 on the right side of the equation is eliminated.
x + 7 = 15y.
Now we are going to divide both sides by 15, thus leaving y by itself.
= 15y / 15.
Since we cannot divide the left side of the equation by 15, it will remain as such. With the y variable completely isolated, our final inverse function will be:
= .
Hopefully, this helps! =)
83 + 96 + 88 = 267
267 / 3 = 89
(89 + x) / 2 = 90
Multiply both sides by 2.
89 + x = 180
Subtract 180 - 89.
x = 91
I'm not a hundred percent sure on this one. I think the answer is neither.
Yes she is correct because 1 divided by 3 will have an infinite number of 3s
