Answer:
The system of inequalities is

The solution in the attached figure
Step-by-step explanation:
<u><em>The question is</em></u>
Write a system of linear inequalities.
Le
x ---> number of scarves knitted per week
y ---> number of knitted sweaters per week
we know that
Mary would like to spend no more than 40 hours per week knitting
The word "No more" means "less than or equal to"
so
----> inequality A
Mary would like to knit at least 5 items per week
The word "at least" means "greater than or equal to"
----> inequality B
Solve the system by graphing
The solution is the triangular shaded area
see the attached figure
Answer:
The leading term is 2x^7. Since n is odd and a is positive, the end behavior is down and up.
90 ÷ 2 is the same as 1/2 of 90.
Either way you get 45.
You can do 109 divide by 100 then multiply it by the percent you need 109/100= 1.09*57=62.13
