Select all expressions that are equivalent to 4x+2(2x-5)-(3-5x)
Arada [10]

For this case we have the following expression:

4x + 2 (2x-5) - (3-5x)

Applying distributive property to the terms within parentheses taking into account that:

- * + = -\\- * - = +

We have:

4x + 4x-10-3 + 5x =

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

4x + 4x + 5x-10-3 =\\13x-13

Thus, an equivalent expression is:

13x-13

Answer:

13x-13

The 1985 Mexico City earthquake measured a magnitude 8.0 on the Richter scale. The Richter scale uses the function M (I) = log (
Travka [436]

Answer:

The correct option is C: I = 10⁸I₀.   

Step-by-step explanation:

The function of the Richter scale is:

M_{(I)} = log(\frac{I}{I_{0}})

Since the magnitude of the earthquake is 8.0, the relation between the intensity, I, with the intensity of the threshold quake, Io, is:

8.0 = log(\frac{I}{I_{0}})

10^{8} = \frac{I}{I_{0}}

I = 10^{8}I_{0}

Therefore, the correct option is C: I = 10⁸I₀.                

I hope it helps you!
