The scatterplot shows x, the high temperature in degrees Fahrenheit (°F), and y, the aquifer level in feet, for ten days in the
same area.
Based on the scatterplot, which equation best represents these data?
y = 656 − 0.1 x
y=661−0.1x
y = 656 − 0.5 x
y=661−0.5x

Given:
Jeffery babysits for 4 dollars per hour and works as a math tutor for 7 dollars per hour.
He is only allowed to work 13 hours total per week.
He wants to make at least 65 dollars.
To find:
The system of inequalities to represent this situation.
Solution:
Let x be the number of hours he babysits per week and y be the number of hours h works as a math tutor.
He is only allowed to work 13 hours total per week. It means sum of x and y must be less than or equal to 13.
He wants to make at least 65 dollars. It means total earnings must be greater than or equal to 65.
Number of hours can not be negative.
.
Therefore, the required system of inequalities contains some equations, and

Answer:
The inequality represents the length of the femur for which the woman had a height greater than 160cm.
Step-by-step explanation:
The given equation is
Where, h is woman's height in centimeters and f is length of the femur in centimeters.
If woman's height is greater than 160cm, then
Substract 60 from both sides.
Divide both sides by 2.5.
Therefore the inequality represents the lengths of the femur for which the woman had a height greater than 160cm.
