What is the domain of the function y=-720t + 3600 ?

Colt1911 [192]

Answer:

We conclude that:

$\mathrm{Domain\:of\:}\:-720t+3600\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

Please also check the attached graph.

Step-by-step explanation:

Given

Given the function

$y=-720t\:+\:3600$

To determine

What is the domain of the function y=-720t + 3600

We know that the domain of the function is the set of input argument values for which the function is real and defined.

Given the function

$y=-720t\:+\:3600$

From the given function, it is clear that the function has no undefined points nor domain constraints.

Therefore, the domain of the function is

$-\infty \:$

Thus, we conclude that:

$\mathrm{Domain\:of\:}\:-720t+3600\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

Please also check the attached graph.

You make $2,800 per month. Rent should be 30% of your monthly income and transportation and food should each be 15%. How much mo

Marysya12 [62]

Answer:

$1260

Step-by-step explanation:

Given data

You make $2,800 per month

Rent= 30% of monthly earning

=30/100*2800

= 0.3*2800

=$840

Transportation and foodt= 15% of monthly earning

=15/100*2800

= 0.15*2800

=$420

Hence the total expenses = 840+420

= $1260
