Given f(x) = the quantity of 2x minus 2 divided by 4, solve for f−1(3).
spin [16.1K]
Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7

Factor completely 2x5 + 10x4 − 22x3.
Luba_88 [7]

Given equation is :

2x^{5}+10x^{4}-22x^{3}=0

Taking out 2x^{3} common we get,

x^{2}+5x-11=0

Now solving this we get,

As 11 is not factor-able, we will solve it using the formula,

x=\frac{-b+\sqrt{b^{2}-4ac}}{2a}

a=1 b=5 and c=-11

we get,

x=\frac{-5+\sqrt{69} }{2} and x=\frac{-5-\sqrt{69} }{2}

What is this I need the answer
Archy [21]
<h3>Answer is  0</h3>

===========================================================

Explanation:

Logarithms are used to solve exponential equations. Specifically if you have a variable in the exponent, then you use a log to isolate the variable.

If we set the given log expression to x, then we can rewrite it into 8^x = 1. The only value of x that works is x = 0.

------------

Or put another way,

8^x = 1

8^x = 8^0 ... replace the 1 with 8^0

x = 0 ... the bases are equal (to 8) so the exponents must be equal

------------

You can use the change of base formula to directly calculate this log

\log_8(1) = \frac{\log(1)}{\log(8)} = \frac{0}{0.903} = 0

. John Gray bought a basic car for $8,250.00, with options that cost $324.00. There's a 6% sales tax in
bogdanovich [222]
Cost of basic car = $8250
Optional cost = $324
Total cost of basic car and optional items for John= (8250 + 324) dollars
                                                                  = 8574 dollars
Then
Percentage of sales tax = 6%
Amount of sales tax = 8574 * (6/100) dollars
               = 514.44 dollars
License and registration fee combined = $50
Then total cost of John in regards to buying the car = 8574 + 514.44 + 50
                                                                                    = 9138.44 dollars
So option "C" is the correct option in regards to the question given.
