PLZ HELP AND SHOW YOUR WORK <3333 Substitution. 3x+2y=11 y=5x-1

liraira [26]

Hey there! :D

Substitute y for 5x-1.

3x+2y=11

y=5x-1

3x+2(5x-1)=11

3x+10x-2=11

13x-2=11

13x=13

x=1

Now, plug that in to find y.

y=5x-1

y=5(1)-1

y=5-1

y=4

(1,4) <== the solution

I hope this helps!

What is the inverse of the function F (X) equals 2X +1

Liono4ka [1.6K]

Answer: $f^{-1}(x)=\frac{x-1}{2}$

Step-by-step explanation:

To find the inverse of a function start by replacing f(x) with x and replace the original x with y.

$f(x)=2x+1\\x=2y+1$

Now solve for y

$x=2y+1\\x-1=2y+1-1\\x-1=2y\\\frac{x-1}{2} =\frac{2y}{2}\\\frac{x-1}{2} =y$

Finally, replace y with the inverse of f(x), $f^{-1}(x)$
