Answer:

A. y = 5x

Step-by-step explanation:

In order to find the answer, all you have to do is see the unit rate, which is the number of balls per minute, and if you look at the chart, it shows that for every 1 minute that passes, 5 balls are thrown, therefore, the answer would be:

y = 5x

Neptune is an average distance of 4.5 × 10^9 km from the Sun. Estimate the length of the Neptunian year using the fact that the

zlopas [31]

Answer:

164.32 earth year

Step-by-step explanation:

distance of Neptune, Rn = 4.5 x 10^9 km

distance of earth, Re = 1.5 x 10^8 km

time period of earth, Te = 1 year

let the time period of Neptune is Tn.

According to the Kepler's third law

T² ∝ R³

$\left ( \frac{T_{n}}{T_{e}} \right )^{2}=\left ( \frac{R_{n}}{R_{e}} \right )^{3}$

$\left ( \frac{T_{n}}{1} \right )^{2}=\left ( \frac{4.5\times10^{9}}}{1.5\times10^{8}}} \right )^{3}$

Tn = 164.32 earth years

Thus, the neptune year is equal to 164.32 earth year.

Find the y? 3x + 6y = 12

kari74 [83]

Could you give Brainliest please???

Answer:

y = 2 - 1/2x

Step-by-step explanation:

So we are given the equation 3x + 6y = 12 and are ask to find y.

To find y you must isolate it first.

3x + 6y = 12

(Subtract 3x to isolate the y term)

6y = 12 - 3x

(Divide both sides by 6 to isolate the variable)

y = 2 - 3/6x

(Simplify)

y = 2 - 1/2x

And that is your answer since there is a second variable.

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

8(2x + 5) = 16x + 40

Step 2: Solve for x

Distribute 8: 16x + 40 = 16x + 40
Subtract 40 on both sides: 16x = 16x
Divide 16 on both sides: x = x

Here we see that x does indeed equal x.

∴ x has an infinite amount of solutions.
