Katle is buying souvenir gifts for her big family back home. She wants to buy everyone elther a key chain or a magne The magnets are on sale for 50 cents each and the key chains cost $1 each. She must purchase at least 24 gifts but to spend less than $20. Let w represent the number of magnets and y represent the number of key chains. 1. Model the scenarlo with a system of Inequalities. 2. Graph the system of Inequalities and choose an appropriate solution for the scenarlo. Use complete sentences to prove why the solution is appropriate.

the answer will be the last one

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
