Answer:
-2<x<1
Step-by-step explanation:
-5 < 8x + 11 < 19
Subtract 11 from all sides
-5-11 < 8x + 11-11 < 19-11
-16 < 8x<8
Divide by 8
-16/8 < 8x/8 <8/8
-2<x<1
We only know the value of <span>f(5)</span>
therefore we need to figure out what we would put in for x in <span>f(<span>1/3 </span>x)</span> to get 5
set
<span><span>1/3 </span>x=5</span><span>x=15
</span>now if <span>x= 15</span> then <span>f(<span>1/3 </span>x)
= f(<span>1/3</span>×15)
= f(5)=8
</span><span>and so
</span><span><span>1/4</span>×8−2=2−1=1
</span>therefore the "corresponding point" is <span><span>(15,1)</span></span>
X/6 - 3 ≥ 2
x/6 ≥ 3+2
x/6≥5
x≥30
