Find the inverse function of g(x) = 2x + 4.g -1(x) = 4x + 2 g -1(x) = 2 x + g -1(x) = x - 2g -1(x) = 2x - 4

Exchange x and y and solve for y

y=2x+4
x=2y+4
2y=x-4
y = x/2 - 2
g(x)=x/2 - 2

PLEASE HELP ME NOW!!
puteri [66]

Answer:

x=4+-2\sqrt{7}

Step-by-step explanation:

To solve, we need to take square root of both sides first:

(x-4)^2=28\\\sqrt{(x-4)^2} =+-\sqrt{28} \\x-4=+-\sqrt{28}

Now we use the property of radical shown below to simplify square root of 28:

Property:  \sqrt{x*y}=\sqrt{x} \sqrt{y}

Now, we have:

x-4=+-\sqrt{28}\\x-4=+-\sqrt{4*7}\\x-4=+-\sqrt{4}\sqrt{7}\\x-4=+-2\sqrt{7}

Now we take 4 to the other side and isolate x:

x-4=+-2\sqrt{7} \\x=4+-2\sqrt{7}

first answer choice is right.

2(x-3)=5(x-3)+10<br><br><br> Need urgent help
ArbitrLikvidat [17]

Step-by-step explanation:

2(x-3)=5(x-3)+10

=> 2x - 6 = 5x - 15 + 10

=> -6 + 15 -10 = 5x - 2x

=> 5x -2x = 15 - 6 - 10

=> 3x = 15 - 16

=> 3x = -1

=  > x =  \frac{ - 1}{3} (ans)
