Answer:
6 kg/m
Step-by-step explanation:
mass m = 3x^2.
rho ρ= dm/dx =6x
ρ(1) =6 Kg/m
linear density is the derivative of mass (m)  with respect to position(x)
that is how fast is the mass changing at that position.
 
        
             
        
        
        
Answer:
(10, 14)
Step-by-step explanation:
To solve this system let's use substitution:
Solve the first equation for x, obtaining x = 24 - y, and then substitute 24 - y for x in the second equation:
3(24 - y) + 5y = 100
Performing the indicated multiplication, we get:
72 - 3y + 5y = 100
Combining like terms results in 72 - 100 = -2y, or -28 = -2y
Thus, y must be 14.
If y = 14, then the first equation tells us that x = 10.
Check:  Is this true?  3(10) + 5(14) = 100  YES
The solution is (10, 14).

Answer:
   g(-5) = 15
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
   g(-5) = -2(-5) +5 = 10 +5
   g(-5) = 15
 
        
             
        
        
        
Yes. If the side lengths are different, you can end up with different angle measurements (example: SSA~ property. You can have two sides that are the same but you can make two different triangles with those side lengths and that one angle.)
