Step-by-step explanation:
<em><u>The question is </u></em>
Identify the domain and the range, using words and inequalities
Let
x -----> the number of kilowatt-hours (kWh) of electricity per month
y ----> the price per month
we know that
Part 1) For the value of x between 0 kWh and 400 kWh
The price is equal to
therefore
The domain is the interval ------> [0,400)
The domain is all real numbers greater than or equal to 0 kWh and less than 400 kWh
The range is ($30)
The range is equal to $30
Part 2) For the value of x equal to 400 kWh or more per month
The domain is the interval -----> [400, infinite)
The domain is all real numbers greater than or equal to 400 kWh
The price is
<em>Find the range</em>
For x=400 kWh
so
The range is the interval -----> [38.8, infinite)
Answer:
1. Let, Jamie needs "$ g" for the trip. Then, according to the question,
g = 600 -------------------(1)
2. Let, Stella needs "$ m" for the trip. Then, according to the question,
m = 600 -------------(2)
3. If Jamie washes x no. of cars and Stella makes y no. of pies, then,
25x ≥ 600 ≥ 15y -------------(3)
4. Yes, Stella can afford to sign up for the trip with the money she earns.
Step-by-step explanation:
Let, Jamie needs "$ g" for the trip. Then, according to the question,
g = 600 -------------------(1)
Let, Stella needs "$ m" for the trip. Then, according to the question,
m = 600 -------------(2)
if Jamie washes x no. of cars for $25 each and Stella makes y no. of pies
for $ 15 each, then, according to the question,
25x ≥ 600 ≥ 15y -------------(3)
Yes, Stella can afford to sign up for the trip with the money she earns. Because, she can make at most 40 pies for $15 each and
$ = $ 600 = The amount of money Stella needs for the trip.
