y=3x+2\\ 3x=y-2\\ x=\dfrac{y-2}{3}\\\\ y^{-1}=\dfrac{x-2}{3}

The inverse of this function is y = \frac{x - 2}{3}

In order to find the inverse of any function, you must start by switching the y and x terms. After doing so, you can then solve for your new y. The result will be the inverse function. The work for this one is done below for you.

y = 3x + 2----> switch the x and y

x = 3y + 2 ----> subtract 2

x - 2 = 3y ----> divide by 3

\frac{x - 2}{3} = y ----> switch the order for consistency

y = \frac{x - 2}{3}

This is now your inverse function.

I need help I would really thank wheeler answers this for me
gavmur [86]
It helps immensely if you know your times tables.

a) 36 = 6*6 = 2*3*2*3 = 2^2*3^2


b) 45 = 5*9 = 5*3*3 = 3^2*5


c) 2 is not a common factor; 3^2 is a common factor; 5 is not a common factor. The greatest common factor is 3^2 = 9.


d) The least common multiple can be found a couple of ways.

.. 1) the product of the distinct factors to their highest powers
.. .. .. 2^2 * 3^2 * 5 = 180

.. 2) the product of the numbers divided by their greatest common factor.
.. .. .. 36 * 45 / 9 = 180

What is the cross-sectional area of a wire if its outside diameter is 0.0625 inch?
Leno4ka [110]

Given that the diameter: d= 0.0625 inch.

So, radius of the wire : r = \frac{0.0625}{2} = 0.03125 inch

Now the formula to find the cross-sectional area of wire ( circle) is:

A = πr²

= 3.14 * (0.03125)² Since, π = 3.14 and r = 0.03125

=3.14 * 0.000976563

= 0.003066406

= 0.00307 (Rounded to 5 decimal places).

Hence, cross-sectional area of a wire is 0.00307 square inches.

Hope this helps you!

HELP pleaseee ASAP I’m stuck
Blizzard [7]

Step-by-step explanation:

using trig, tangent is equal to opposite over adjacent.

in this case, the angle is 45, opposite is 7, and adjacent is a.

thus tan 45° = 7/a

solve for a to get a = 7/tan 45° = 4.32
