Answer:
Step-by-step explanation:
Let h be the number of hats Elliott makes and s be the number of scarves she makes.
Each hat uses 0.2 kilograms of yarn and each scarf uses 0.1 kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats. This is expressed as
h = 2s
The total number of hats and scarves that she wants to make is 20. This is expressed as
h + s = 20
Therefore, the system of equations that represents this situation are
h = 2s
h + s = 20
x^4 + 7x^3 - 2x^2 - 9x - 3 - (10/x+8)
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

The solution is the interval -----> (-∞,8)

The solution is the interval -----> [3,∞)
The solution of the system is equal to
[3,∞)∩ (-∞,8)-------> [3,8)
All real numbers greater than or equal to 3 and less than 8

Answer:
2^x = 1/4.
Step-by-step explanation:
log2 1/4 = x
By the definition of a log:
2^x = 1/4.
