Answer:
(1, 0 )
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x =
, then
y = (x + 2) - 1
to find the zero let y = 0 , that is
(x + 2) - 1 = 0 ( add 1 to both sides )
(x + 2) = 1 , then
x + 2 = = 3 ( subtract 2 from both sides )
x = 1
the zero is (1, 0 )
Answer:
The system of equation that represent this situations are;
Also 5 hats and 10 scarves can be prepared from 2 kg of yarn.
Step-by-step explanation:
Let number of hat Chevy makes be h.
Also Let number of scarves Chevy makes be s.
Given:
Total Amount of yarns = 2 kg
Total number of items = 15
Since Items need to make are hat and scarves.
Hence the equation can be represented as;
Again Given:
Each hat uses 0.2 kilograms of yarn.
each scarf uses 0.1 kilograms of yarn.
Hence the equation can be represented as;
Hence the system of equation that represent this situations are;
Now Solving these to find number of hats and number of scarves.
Multiplying equation 2 with 10 we get;
Now Subtracting equation 1 from equation 3 we get;
Now Substituting the value of h in equation 1 we get;
Hence 5 hats and 10 scarves can be prepared from 2 kg of yarn.
