Total is 68 and the perm is 2 times as much as her haircut and her lunch is $5
so...
2h+h+5= 68 (add like terms)
3h+5 = 68 (subtract 5 from both sides)
-5 - 5
3h = 63 (divide by 3)
h= 21
so if her haircut is 21 dollars
21*2= $42
her perm cost 42 dollars
Answer:
Step-by-step explanation:
Derivative indicates rate of change of dependent variable with respect to independent variables. It indicates the slope of a line that is tangent to the curve at the specific point.
Given:
Number of bees is modeled by the function 
The daily high temperature is increasing at a rate of 2 °F per day when the number of bees spotted is 100.
To find:
rate of change of number of bees when 100 bees are spotted
Solution:
Differentiate with respect to t,
Put 
At x = 100,
Answer:

Answer:
A= -4
B= 4
C= 1/4
D= -1/4
Step-by-step explanation:
I see u counted which is good. remember it's rise over run so for a u got up down 4 over 1. that's why the slope would be -4. You figure out the other ones the same way.
