Step-by-step explanation:
- s ( x ) = 2 - x²
- t ( x ) = 3x
- s ( t ( -7 ) ) = ?
--------------------------
- t (-7) = 3 * ( -7 ) = -21
- s ( t ( -7 ) ) = s ( -21 ) = 2 - ( -21 )² = 2 - 441 = - 439
- s ( t ( -7 ) ) = -439

Sample Answer for Plato
<span>20-9x=11
-9x=11-20
-9x= -9
x= -9/(-9)
x=1
4(2x+1)=8
2x+1=8/4
2x+1=2
2x=2-1
2x=1
x=1/2
x=0.5
5(2x+5)=-15
2x+5= -15/5
2x+5= -3
2x= -3-5
2x= -8
x= -8/2
x=-4
3(8x+1)=-21
8x+1= -21/3
8x+1= -7
8x= -7-1
8x =-8
x= -8/8
x= -1
