PLEASE HELP<br><br> Which of the following is the inverse of f(x)=3-x/5
BabaBlast [244]

Answer:

f^-1(x) = 3 - 5x, second option

Step-by-step explanation:

To determine the inverse simply interchange the variables and solve for y;

f(x) = 3 - x / 5 -> Interchange the variables

x = 3 - y/5 -> Multiply either side by 5

5x = 3 - y -> Subtract three from either side

- y = 5x - 3 -> Divide either side by - 1

y = - 5x + 3

Your solution is f^-1(x) = 3 - 5x

Express as a trinomial (3x+8) (x+10)
docker41 [41]

Answer:

3x^{2} +38x+80

Step-by-step explanation:

Hello!

A trinomial is a expression consisting of three different terms

To turn this into a trinomial we multiply everything to each other

<u>                     3x                     </u>

3x * x = 3x^{2}

3x * 10 = 30x

<u>                     8                      </u>

8 * x = 8x

8 * 10 = 80

Now we put them all together in an equation

3x^{2} +30x+8x+80

Combine like terms

3x^{2} +38x+80

The answer is 3x^{2} +38x+80

Hope this helps!
