The correct sequence to find the inverse of y=3x/8+x

1 answer:

8 0

Answer:

You MUST use parentheses around denominator 8+x, or ANY denominator that consist of more than a single number of variable.

Also, don't use lower case and upper case interchangeably.

In algebra, x and X are different, as are y and Y.

f(x) = y = 3x/(8+x)

Switch x and y, solve for y:

x = 3y/(8+y)

x(8+y) = 3y

8x+xy = 3y

8x = 3y−xy

8x = y(3−x)

y = f⁻¹(x) = 8x/(3−x)

lozanna [386]

Answer:

Step-by-step explanation:

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the points (5, 4) and (-3, -1). Substitute:

$d=\sqrt{(-3-5)^2+(-1-4)^2}=\sqrt{(-8)^2+(-5)^2}=\sqrt{64+25}=\sqrt{89}\approx9.43$
