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.
Answer:
They are 5 I think
Step-by-step explanation:
It should be correct
Answer:
c
Step-by-step explanation:
Subtract 17 by 3, and then you get 14, multiply 4 times 3 2/3 which gives you 14 with a fraction 2/3 so the answer is c
Answer:
-17
Step-by-step explanation:
-6-11=-17
Answer:
y = 0
Step-by-step explanation:
It is always a good idea to look at the question and make some observations about it. Here, you might observe ...
- all of the bases are powers of 3: 243 = 3^5; 9 = 3^2
- y is a factor of every exponent
The latter observation is important, because it means that when y=0, every exponential expression has a value of 1. Hence y = 0 is a solution.

To solve the equation, you can write it in terms of powers of 3.
(3^5)^(-y) = (3^-5)^(3y)·(3^2)^(-2y)
3^(-5y) = 3^(-15y)·3^(-4y)
3^(-5y) = 3^(-19y)
-5y = -19y . . . . . . . . equating exponents; equivalent to taking log base 3
14y = 0 . . . . . . . . . . add 19y
y = 0 . . . . . . . . . . . one solution
______
The rules of exponents we used are ...
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
1/a^b = a^-b
