Answer:

\frac{15x-5}{5x+6}

Step-by-step explanation:

Given

f(x) = \frac{3x-5}{x+6}

To evaluate f(5x) substitute x = 5x into f(x)

f(5x) = \frac{3(5x)-5}{5x+6} = \frac{16x-5}{5x+6}

I only really need the domain and range, intervals, and end behavior. My Precalculus class never covered piecewise functions so
Serjik [45]

(a)

Domain:

we know that domain is all possible values of x for which any function ios defined

Here, curve is defined for all values of x

so, domain is

(-\infty,\infty)

Range:

Range is all possible values of y for which x is defined

minimum value of y is -4

maximium value of y is +inf

so, range is

[-4,\infty)

(b)

x-intercept:

It is the value of x where f(x)=0

so, the point where curve intersects on x-axis

and we get

2x^2-4=0

x=\sqrt{2}

and

x=-5

(c)

Increasing interval:

where curve is moving upward

we can see that

(0,\infty)

Decreasing interval:

where curve is moving downward

we get

(-\infty,-1)U(-1,0)

Constant:

constant means horizontal line

there is no horizontal line here

so, it does not exist

(D)

End behavior:

when x-->+inf

y is moving upward

so, y---->+inf

when x-->-inf

y is moving upward

so, y---->+inf

(E)

we can see that curve jupms at x=-1

so, there is discontinuity at x=-1

and this is jump type of discontinuity

(F)

For odd:

f(-x)=-f(x)

For even:

f(-x)=f(x)

we can see that none of them holds true

so, this is neither

Sum of all natural numbers from100to300 which are divisible by 4and 5 is​
My name is Ann [436]

If x is a number that is both divisible by 4 and 5, then

\begin{cases}x\equiv0\pmod4\\x\equiv0\pmod5\end{cases}

4 and 5 are coprime, so we can use the Chinese remainder theorem to solve this system and find that x=20n is a solution to the system, where n is any integer. Simply put, any multiple of 20 fits the bill.

Now, there are 11 numbers between 100 and 300 that are divisible by 20 (100, 120, 140, and so on). We have 20n=100 when n=5, so the sum we want to compute is

\displaystyle\sum_{n=5}^{15}20n=\boxed{2200}

Calculate the deferred tax liability given the following Items Incurred In 2020 by Company B. Bonuses are tax deductible only in
german

The deferred tax liability in 2020 for Company B.  would be $372.

<h3>How much of the deferred tax liability is incurred?</h3>

First, we have to find the taxable income:

= $86,000 + $6,500 + $3,500 -$ 4,000 - $4,700 - $2,630

= $84,670

Now, as the accounting income of $86,000 is more than the taxable income of $84,670, there will be a deferred tax liability of:

= ($86,000 - $84,670) * 28%

= $1,330 * 28%

= $372

Therefore, the deferred tax liability in 2020 for Company B.  would be $372.
