Let's break down the given expressions step-by-step.
1. Evaluating [tex]\( y \)[/tex]:
[tex]\[ y = \frac{4}{3} + 2 \][/tex]
To simplify this, first evaluate [tex]\(\frac{4}{3}\)[/tex]:
[tex]\[ \frac{4}{3} \approx 1.3333333333333333 \][/tex]
Next, add 2 to this value:
[tex]\[ y = 1.3333333333333333 + 2 = 3.333333333333333 \][/tex]
So, we have:
[tex]\[ y \approx 3.333333333333333 \][/tex]
2. Relating [tex]\( y \)[/tex] to [tex]\( x \)[/tex]:
[tex]\[ 3y = x^{-3} \][/tex]
Substitute the value of [tex]\( y \)[/tex] that we found into the equation:
[tex]\[ 3 \times 3.333333333333333 \approx 10.0 \][/tex]
Hence,
[tex]\[ x^{-3} \approx 10.0 \][/tex]
In summary,
- The value of [tex]\( y \)[/tex] is approximately [tex]\( 3.333333333333333 \)[/tex].
- The expression [tex]\( 3y \)[/tex] simplifies to approximately [tex]\( 10.0 \)[/tex], thus [tex]\( x^{-3} \approx 10.0 \)[/tex].
