HELP<br> Solve the following systems using the elimination method.<br> 5x+2y = -16<br> 4x-2y = 16

velikii [3]

Answer:

x= 0 , y= -8

Step-by-step explanation:

Add the 2 equations together, you would get:

9x = 0

Divide both sides by 9:

x = 0/9

x=0

Substitute the value of x in one of the equations to get the value of y, I picked the first one (5x+2y = -16)

5(0) +2y = -16

0+2y = -16

2y = -16

Divide both sides by 2:

y = -8

Elodia [21]

Answer: 9.54731702 astronomical units

Step-by-step explanation:

Given: The orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula $P=a^{\frac{3}{2}$ .

Saturn’s orbital period P = 29.5 years

Substitute this value in the equation above, we get

$29.5=a^{\frac{3}{2}}\\\Rightarrow(29.5)^{\frac{2}{3}}=a\\\Rightarrow\ a=9.54731702\text{ astronomical units}$

Hence, its distance from the sun = 9.54731702 astronomical units.
