Help me please ASAP I only have a few minutes what is 2x - 3y = 4
X = 2y + 1 in system of equations by substitution & can you show work please or I won’t get my points I really need a good grade ?

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.

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
