Answer:
D
Step-by-step explanation:
(1/3)^x=27^(x+2)
3^(-x)=3^(3(x+2))
3^(-x)=3^(3x+6)
<span>2x − 3 < x + 2 </span>
<span>∴ x − 3 < 2 </span>
<span>∴ x < 5 </span>
<span>x + 2 ≤ 3x + 5 </span>
<span>∴ 2 ≤ 2x + 5 </span>
<span>∴ -3 ≤ 2x </span>
<span>∴ -3/2 ≤ x </span>
<span>-3/2 ≤ x < 5</span>
Answer:
2 1/2

Hi,
Your answer would be B
Hoped I Helped
To
answer this set of questions, all we have to do is just to substitute the value
of x in F(x) to the given f(x) equation.
By
substitution and following PEMDAS rule:<span>
F(-1)=2(-1)³-3(-1)²+7=5</span>
F(1)=2(1)³-3(1)²+7=6
F(2)=2(2)³-3(2)²+7=11
Therefore the answers
are 5, 6 and 11.
