The density of Venus, compared to Earth having a density of 1,
guapka [62]

Answer:

Mercury

Step-by-step explanation:

We'll translate this into ratios.

First, V:E = 0.943:1

Then, M:E = 0.983:1

We already have their density in terms earth's density. They are in the same unit. So, we can compare them directly, with greater ratio means greater density. It's clear that Mercury has the greater density.

<u>Algebra I</u>

  • Functions
  • Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = -2x + 3

g(x) = 2x + 3

f(3) is x = 3 for function f(x)

g(7) is x = 7 for function g(x)

<u>Step 2: Solve</u>

  1. Substitute in <em>x</em> [Functions]:                                                                               f(3) = -2(3) + 3, g(7) = 2(7) + 3
  2. Substitute in functions:                                                                                     f(3) + g(7) = -2(3) + 3 + 2(7) + 3
  3. Multiply:                                                                                                             f(3) + g(7) = -6 + 3 + 14 + 3
  4. Add:                                                                                                                   f(3) + g(7) = -3 + 14 + 3
  5. Add:                                                                                                                   f(3) + g(7) = 14
