An electrician charges a set fee for every house call and then charges an hourly ratedepending on how long the job takes. The to

tal cost of the electrician's services can bedetermined using the equation C = 65 + 60t, where t is the number of hours theelectrician spends at the house working. What is the slope of the equation and what isits interpretation in the context of the problem?

We have the equation:

C(t)=65+60t

Given the slope-intercept formula for the equation of the line, we have the following:

\begin{gathered} y=mx+b \\ m\colon\text{ slope} \\ If\text{ C=65+60t} \\ \Rightarrow slope\text{ = 60} \end{gathered}

Now, since we have that t is the number of hours the electrician spends working, the slope of the function represents the hourly rate charged.

Which statement best describes g(x) = 3x + 6 - 8 and the parent function f(x) = } ?
kumpel [21]

Answer:

In general gf(x) is not equal to fg(x)

Some pairs of functions cannot be composed. Some pairs of functions can be composed only  for certain values of x.

Only with they can be composed some values of x are the ranges of g(x) and f(x) are the same, and their domains are also the same. Or else lies inside it.

Step-by-step explanation:

g(x) = 3x + 6 - 8, f(x) = √x.

The domain of a composed function is either the same as the domain of the first function, or  else lies inside it

The range of a composed function is either the same as the range of the second function, or else lies inside it.

Or vice versa

Now only positive numbers, or zero, have real square roots. So g is defined only for numbers

greater than or equal to zero. Therefore g(f(x)) can have a value only if f(x) is greater than or

equal to zero. You can work out that

f(x) ≥ 0 only when x ≥3/2

Answer:

21 in

Step-by-step explanation:

by the Pythagorean theorem we have

841=400+x^2\\\\x^2=441\\\\x=21

notice that the 841 and the 400 don't go squared because they already squared!

Step-by-step explanation:

hi again

because the cornets show that -4 and -2 are also by -4 and -6 so that would =x+1 and x-5
