Imagine you have a job where you earn $700 each week after taxes. Your monthly living expenses include $725 for rent, $125 for u
Softa [21]

The monthly income is $844.

Given:

  • Weekly earning after taxes is $700
  • Monthly rent is $725
  • Monthly expense for utilities is $125
  • Monthly expense for cable/internet is $120
  • Monthly expense for cellphone is $35
  • Monthly expense for bus fare is $48
  • Minimum monthly payment of credit card debt is $78
  • Monthly expense for groceries is $600
  • Monthly expense for dining out and entertainment is $225

To find: The monthly income

The monthly income refers to the amount of money left over each month after paying all expenses.

Evaluating, we have,

The total monthly expense = $(725 + 125 + 120 + 35 + 48 + 78 + 600 + 225)

That is, the total monthly expense is $1956.

It is given that weekly earning after taxes is $700. Since a month contains 4 weeks, we can say that monthly earning after taxes is $(700 \times 4), that is, $2800.

Then, monthly income is given by the difference between the monthly earnings and the monthly expenses. So, monthly income is $(2800-1956), that is, $844.

The monthly income is $844.

How does the graph of g(x)=1/x-5. +2 compare to the graph of the parent function f(x)=1/x
malfutka [58]

Answer:

x value of vertical asymptote and y value of horizontal asymptote

Step-by-step explanation:

The graph of 1/x approaches infinity as x approaches 0 (the vertical asymptote)

As x gets either bigger or smaller, 1/x approaches the x-axis (from above on the positive side, from below on the negative side) (the horizontal asymptote)

Consider 1/(x-5) + 2, at what value of x does the graph 'go nuts' ?

When the bottom of the fraction becomes 0, x - 5 becomes 0 when x = 5, so the vertical asymptote of g(x) is at x=5

What value of y does f(x) approach as x gets more positive or more negative - as x gets bigger (as an example), y approaches 0

What y value does g(x) approach as x gets bigger?  Well, as x gets big, 1/(x-5) gets small, approaching 0.  The smallest 0 + 2 can get is 2, so y=2 is the horizontal asymptote
