Answer: f⁻¹(x)=(x-7)²
Step-by-step explanation:
To find the inverse function, we want to switch the y with the x and vice versa. Then we solve for y.
[switch y with x and x with y]
[subtract both sides by 7]
[square both sides]
Now, we know that f⁻¹(x)=(x-7)².
Answer:
The answer is C)
Step-by-step explanation:
In order to fully solve a system of equations, you need both variables, x And y. Therefore he has to go back and solve for x
Answer:
51
Step-by-step explanation:
3.6=6333.34
Divide that by 125 and you have
50.6 but round up to 51
I think that the answer would have to be 7,863. I'm not sure if I did this right or not but all I did was subtract the two numbers and I got 7,863.
