Px-2= 4x+x+9

First what you should do is subtract the 2 on both sides

You’ll get px = 4x+x+7 then add the x to 4x

Px= 4x^2 +7

Dived the x on the left on both sides like this px/x = 4x^2+7/x

P= 4x+7

If a is a negative number, then a(1/a) is equal to -1. If a is a negative number and b is a negative number, then product ab is

Firdavs [7]

Both claims are false. In fact, $a$ and $\frac{1}{a}$ are one the multiplicative inverse of the other. This means, by definition of multiplicative inverse, that

$a \cdot \dfrac{1}{a} = 1 \quad\forall a \in \mathbb{R}$

So, it doesn't matter if $a$ is positive or negative: the multiplication of one number and its inverse will always be 1: for example,

$(-2) \cdot \dfrac{1}{-2} = \dfrac{-2}{-2} = 1$

Similarly, when you multiply two number, the sign of the product depends on the sign of the factors as follows:

$(+) \cdot (+) = (+)$
$(+) \cdot (-) = (-)$
$(-) \cdot (+) = (-)$
$(-) \cdot (-) = (+)$

So, the multiplication of two negative numbers is a positive number.

The length of a planet's orbit around a star is approximately 17,650,000 km.

daser333 [38]

Answer:

1150 km/hr

Step-by-step explanation:

Formula for Average Speed is given as = Distance in Kilometers/ Time in Hours

In the question we are given the following parameters.

The length of a planet's orbit around a star = Distance = 17,650,000 km.

Time taken to complete a full orbit = 640 Earth days

Step 1

We need to convert the time in days to hours

1 Earth day = 24 hours

640 Earth days =

We cross multiply

640 Earth days × 24 hours

= 15360 hours.

Step 2

Average Speed = Distance in Kilometers/ Time in Hours

Average Speed = 17,650,000 km. /15360 hours

Average Speed = 1149.0885417 km/hr

Approximately to 3 significant figures=

1150 km/hr

Therefore, the planets average speed in kmh-1 to 3sf is 1150 km/hr
