Solve 3.5x + 10 &lt; -30
romanna [79]

Answer:

x < <em>-11.4285......</em>

Step-by-step explanation:

<u>Step 1:  Subtract 10 from both sides</u>

3.5x + 10 - 10 < -30 - 10

<em>3.5x < -40</em>

<u>Step 2:  Divide both sides by 3.5</u>

3.5x / 3.5 < -40 / 3.5

<em>x < -11.4285......</em>

Answer:  x < <em>-11.4285......</em>

What is the value of A when we rewrite (32/5)^-2x as A^x​
defon

Answer:

(\dfrac{25}{1024})^x

Step-by-step explanation:

The given expression is :

(\dfrac{32}{5})^{-2x}

We need to rewrite it in the form of A^x.

We know that, (\dfrac{1}{x})^{-a}=x^a

So,

(\dfrac{32}{5})^{-2x}=(\dfrac{5}{32})^{2x}\\\\=(\dfrac{5^2}{32^2})^x\\\\=(\dfrac{25}{1024})^x

So, A=\dfrac{25}{1024}. Hence, this is the required solution.
