I need help with this problem, it's a select multiple with 8 to choose from, please put the answer by saying which letters it is for the multiple-choice. I will give brainliest. You are trying to figure out what a could be without multiplying. Select each value of a for which you can solve the system by elimination without multiplying first.

ax−7y=−13
8x−6y=−2
option a. -7
option b: 42
option c: -6
option d: 6
option e: -2
option f: -8
option g: 8
option h: 7

Write in the answer area like this, for example:

option b, option e, option h.

cant open file sorry!

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.
