Jesse has been asked to graphically solve the simultaneous equations: = + 3, = 2 − 4He has drawn the graph shown. Jesse says that there is no answer to the simultaneous equations.

for the points

step-by-step explanation:

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

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.
