Which values for A and B will create infinitely many solutions for this system of equations? 4 x minus A y = 15. Negative 4 x + 6 y = B.
A = negative 6, B = 15
A = 6, B = 15
A = 6, B = negative 15
A = negative 6, B = negative 15

 C) A = 6, B = -15

Step-by-step explanation:

In order to have infinitely many solutions, you must end up with 0 = 0 when adding the equations together.

 4x  -  Ay  =  15

-4x  + 6y  =  B  

    (6 - A)y = 15 + B

       ↓               ↓

  6 - A = 0      15 + B = 0

        6 = A             B = -15

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
