Substitute 3 for wherever m is. Answer is 4
To double you have to multiply by 2.
13×2=26
Answer:
y=x-3/15
Step-by-step explanation:
f(x)=15x+3/y=15x+3
f-1(x) is an inverse function, which means you gotta swap the x an the y:
x=15y+3
The goal is to get y alone, so you minus 3 on both sides to get
x-3=15y
And then divide both sides by 15 to get y alone
x-3/15=y
Here is an example: If you go 100 miles every 2 hours, what is the unit rate? The unit rate would be 50 miles. Here is all you have to do. You divide (in my case) miles by (in my case) 2 hours, which equals 50 miles. Does that help?
