Step-by-step explanation:
Since the scale factor is 2:7, you can divide the given number by 2 then multiply it by 7, so 12/2x7=42
Factor out the coefficient of the variable 2/3 j - 2/9
Answer
2/3j-2/9 = 2/3j-2/3*1/3 = 2/3(j-1/3)
Step-by-step explanation:
f(x)=x²-1, f(x-1)=(x-1)²-1
=(x-1)(x-1)-1
=(x²-x-x+1)-1
=x²-2x+1-1
=x²-2x=0
x²=2x
x=2
