MORE STUFF
Step-by-step explanation:
AD STUFF TO STUFF AND YOU GET MORE STUFF
Answer is <span>7x^2-3x+7
hope this helps</span>
Part a) Use a system of inequalities to model the scenario
Let
x-------> represent babysitting hours
y-------> represent tutoring hours
we know that
--------> inequality
--------> inequality
Part b) Use the model created in part A to create a graph representing Jeanne’s probable income earned and possible number of hours worked this week
we know that
--------> inequality
This inequality represent Jeanne’s possible number of hours worked this week
Using a graph tool
the solution of this inequality is the shaded area
see the attached figure N
--------> inequality
This inequality represent Jeanne’s probable income earned this week
Using a graph tool
the solution of this inequality is the shaded area
see the attached figure N
Part c) Analyze the set of coordinate values that represent solutions for the model created in part A. Choose one of the coordinates within the solution and algebraically prove that the coordinate represents a true solution for the model
we have the system of inequalities
--------> inequality
--------> inequality
the solution of the system of inequalities is the shaded area
using a graph tool
see the attached figure N
Let
------> see the attached figure N
The point belongs to the shaded area, so it is a system solution.
If the point is a solution, it must satisfy both inequalities.
Prove algebraically
substitute the value of x and y in the inequalities
inequality
------> is ok
inequality
-------> is ok
the point A satisfy both inequalities
therefore
the point A is a solution of the system
So this is going to be alot of writing to show my thinking but ill bold the answer.

that is 6 (that equal 4 or 8) out of 25
so your ratio would be 6:19
Answer:
Question 3 of 10 The answer should be 7
Step-by-step explanation:
The reason is because if it is out of 100 7/100 is still 7%
