The table shows the average distance from the sun for each of three planets, rounded to three significant figures. The average distance from Earth to the sun is defined as 1 astronomical unit. What is the distance, in astronomical units, from Mars to Jupiter? Round your answer to the nearest hundredth.

Answer explanation

3.68

4.84-1.42 = 3.42

3.42/0.93 = 3.677419...

Select all of the equations that represent linear functions.

• y = x

• y = 2x

• y = x^2

• y = 2/x

• y = x/2

Two cylinders, A and B, are created. Cylinder A has volume V. Cylinder B has the same height as cylinder A. Cylinder B has half the diameter of cylinder A. Create an expression that represents the volume of cylinder B in terms of V.

A system of linear equations has no solutions. One of the equations of the system is shown: y = 2x - 1. Which equation could be the other equation of the system?

• y = -1/2x + 1

• y = -2x - 1

• y = 1/2x + 2

• y = 2x + 2
