Trey's : $20+ $0.80song
Deb's : $21 + $0.60 song

20+0.8s = 21+0.6s
0.8s-0.6s= 21-20
0.2s=1
then s = 1/0.2 = 5

so the monthly charge will be the same for both clubs for 5 songs.

and it will cost $20+$0.80(5)= $20+$4= $24.

300=9b
b= about 33

100=9b
b=about 11

Is x = -12 a solution of x^2 +10x+25=49?

Tresset [83]

Answer:

Yes

Step-by-step explanation:

${x}^{2} + 10x + 25 = 49 \\ {x}^{2} + 10x + 25 - 49 = 0 \\ {x}^{2} + 10x - 24 = 0 \\ (x + 12)(x -2 ) = 0 \\ \\ x + 12 = 0 \\ x = - 12 \\ \\ \\ x - 2 = 0 \\x = 2$
