Step-by-step explanation:

f(x) = x / (x - 7) = 1 + 7 / (x - 7).

The domain of f(x) depends whether the denominator of the rational expression is non-zero.

When (x - 7) = 0, x = 7.

Hence domain of f(x)

= All real values of x excluding 7. (C)

Find the equation of the line with slope = 6 and passing through (-9,-58). Write your equation in the form y = mx+ b
stira [4]

Answer:

<u>y=6x-4</u>

Step-by-step explanation:

<u>What we know</u>

  • the slope is 6
  • our point is (-9,-58)

-9 is x and -58 is y so we have to find the y-intercept y=mx+b is also the formula for this

-58=6(-9)+b

-58=-54+b

-58=54+b        - we changed -54 to a positive 54

54-58=-4

y=6x-4

Two competing gyms each offer childcare while parents work out. Gym A charges $9. 00 per hour of childcare. Gym B charges $0. 75
Xelga [282]

Since the workouts are normally on hour scale, thus the first comparison of $9.00 per hour of childcare is more appropriate here.

<h2>Given that:</h2>
  • Gym A charges $9.00 per hour of childcare.
  • Gym B charges $0.75 per 5 minutes of childcare

<h2>How to find which scale is appropriate when?</h2>

Firstly try to find what is the usual scale used for that work.

The usual scale used for given specified work is mostly the appropriate scale.

For Gym case, people are not coming and going in minutes scale, but they count in hours and will be able to comprehend the hour scale better.

Both Gym although offer same price (since $0.75 per minute is equal to $9.00 per hour), but the cost Gym A specifies is more easy to understand for normal public, thus it is more appropriate scale.
