To find f^{-1} (x), you can switch the x and the y(which is f(x)).

So instead of f(x)=\frac{-7}{4x-5}, it will be:

x = \frac{-7}{4y-5}

Now you need to find "y".

You first multiply (4y - 5) on both sides

x(4y - 5) = -7

Next divide "x" on both sides

4y - 5 = \frac{-7}{x}

Add 5 on both sides

4y = \frac{-7}{x} +5

Divide 4 on both sides to get "y" by itself

y = \frac{7}{4x} +\frac{5}{4}


f^{-1} = \frac{7}{4x} +\frac{5 }{4}

Given 2x+y=6 perform the necessary operations to put equation into the proper general form.Explain in complete sentences how you
VashaNatasha [74]

Answer:

2x + y -6 = 0

Step-by-step explanation:

The general form is Ax+By + C= 0. It requires that A and B be greater than 1 (not fractions or decimals) and A is positive. This equation is 2x + y = 6 is almost already in the form.  Subtract C to both sides to make it general form. 2x + y - 6 =0. The coefficients of the x and y are greater than 1 and 2 is positive. This meets the requirements.

Let's solve your equation step-by-step.

<span><span>2<span>(<span>p+1</span>)</span></span>=18

</span>Step 1: Simplify both sides of the equation.

<span><span>2<span>(<span>p+1</span>)</span></span>=18

</span><span>Simplify: (Show steps)

</span><span><span><span>2p</span>+2</span>=18

</span>Step 2: Subtract 2 from both sides.

<span><span><span><span>2p</span>+2</span>−2</span>=<span>18−2

Compute F(s), the Laplace transform of f(t) = e^(5t) (t^2 +4t +7)
MakcuM [25]

Recall that

\mathcal L_s\{t^ne^{ct}\}=\dfrac{n!}{(s-c)^{n+1}}

Then

F(s)=\dfrac2{(s-5)^3}+\dfrac4{(s-5)^2}+\dfrac7{s-5}
