DOUBLE JEOPARDY 8t-8 what is the variable
t
x squared + 2/3x + 1/9=0
x=-1/3
R + 4 > 8; r =2
no
26-4s=9s
s=2
-8+7f=G What is the coefficient?
The coefficient is 7.
Factor (a) n squared + 8n + 16 and (b) 4x squared - 12x + 9
4x squared - 12x +9 = (2x - 3)squared.
DOUBLE JEOPARDY Three times a number k minus 5/3 is no more then 4/9
3k-5/3 is less than or equal to 4/9
5p-9 = 2p +12
p=7
1+1=x
what is x
