Answer:
Step-by-step explanation:
Domain: x
Range: f(x) {or y}
An example of a point for this equation would be (1 ,2) where 1 would be the domain (or x) and the range (or y) would be 2. Hope this helps :)
For this case we must find an expression equivalent to:

By definition of power properties we have to:

So, rewriting the expression we have:


By definition of multiplication of powers of the same base, we put the same base and add the exponents:

Answer:
Option B
The answer for this question is chord
Step-by-step explanation:
let E be weight of expensive nuts, C be cheaper nuts
E*8+C*5=10*6 value equation
E+C=10 mass equation
Solve it by any method, I will do determinants
Det: 8-5=3
E= (60-50)/3=10/3 =3.33 lb
C= 80-60 /3=20/3 =6.66 lb
