Points A and B have opposite x-coordinates but the same y-coordinates. How many units away are each of the points from the y-axi

Maurinko [17]

Answer:

They are both x units away from the y-axis.

Step-by-step explanation:

The x coordinates are x and -x so they are both x units away from the y-axis. The total distance between the 2 points is x -(-x) = 2x units.

What is the value of g? 25(g−7)=3 Enter your answer in the box

Ratling [72]

First open the bracket by multiplying with 25

25g -25×7 =3

25g -175 =3

Add 175 to both sides

25g -175+175= 3+175

25g = 178

g = 178/25 is the value.

when solving this, do i take it out of the parenthesis or make it into a square root? because its very confusing.

Licemer1 [7]

Finding the inverse function:

We are given a function y = f(x). To find the inverse function, we exchange x with y in the original function, and then isolate y.

We are given the function:

$f(x)=(x+7)^5$

$y=(x+7)^5$

Changing x with y

$x=(y+7_{})^5$

Now, we have to isolate y. So

$(y+7)^5=x$

We can apply the fifth root to both sides. So:

$\sqrt[5]{(y+7)^5}=\sqrt[5]{x}$ $y+7=\sqrt[5]{x}$ $f^{-1}(x)=y=\sqrt[5]{x}-7$
