Answer:
The practical domain of the function is [30,32].
Step-by-step explanation:
The given function is

where, p(h) represents the Vonda's weekly pay as a function of hours worked.
She pays a one time $250 chair rental fee, and earns $40 per hour that she works.
Domain is the set of all possible inputs.
The possible domain of the given function is all real numbers but the number of hours can not be negative, therefore h>0.
It is given that Vonda works between 30 and 32 hours per week at a hair salon. So,

Therefore practical domain of the function is [30,32].
Let...
l=length
w=width
Because we know that the perimeter is 90, we can make this equation...
2l+2w=90
Because we know that the length is 5 feet less than 4 times the width, we can make this equation...
l=4w-5
We can solve this system through substitution...
2(4w-5)+2w=90
8w-10+2w=90
10w=100
w=10 ft
l=4(10)-5=35 ft
Answer:
here = − x + 14
Step-by-step explanation:
Answer:
y= (3/4)x+2
Step-by-step explanation:
You know it can't be the 1st or the last because the fraction in the parenthesis is the slope. And between 2nd and 4th... a -2 is going to make it go through 0,-2. Therefore, it can only be y= (3/4)x+2
