Solution:
A family of 3 children and 2 adults visited a health club. The club charges $y an hour for each child and $x an hour for each adult.
First we make inequality according to question.
In a family number of children 3
Charge for 1 child = $y per hour
Charge for 3 children = 3y
Charge for 1 Adult = $x per hour
Charge for 2 adults = 2x
If the family does not want to s[end more than $30 an hour at health club.
Where, x and y should be greater than 0.
Now we make the graph of this inequality.
First we take equality of equation and then find x and y table.
2x+3y=30
x y
0 10
6 6
15 0
Answer:
Slope = -3
Step-by-step explanation:
Slope of a straight line graph is given by; change in y ÷ change in x
Slope =
=
= -3
Well... looking at how to question is defining things.....i think this is a multiple choice question.....
Given:
"y" represents the population
"x" represents the number of years
duration = 2000 - 1990 = 10 years
population increase = 2700 - 1200 = 1500
Now,
<u></u><u>It says linear equation........</u><u>, So, we have to assume that every ten years the population increases by a fixed </u><u>amount that is 1500 people every 10 years.</u><u />
Now,
Every 10 years, the population increases by 1500
Every 1 year , the population increases by 1500 / 10
= 150
Now,
The equation in determining the population is:
y = 150x + 1200
