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

Add.<br><br> Express your answer in simplest form. <br><br><br> 5/10+3/10
AlexFokin [52]
Rules in adding fractions:

1) Make sure that they have common denominator.
5/10 + 3/10

2) Since both fraction have a denominator of 10, add the numerator and place the sum above the denominator

5/10 + 3/10 = (5 + 3)/10 = 8/10

3) Simplify the fraction
8/10 can still be simplified into 4/5

8 ÷ 2 = 4
10 ÷ 2 = 5

5/10 + 3/10 = 4/5
