The earth is about 150 million kilometers from the sun. the orbit around the sun is not a perfect circle, but is approximately a circle. if the orbit of the earth around the sun were circular, what would be the equation if the origin of the coordinate system were placed at the sun? x² + y² = (150,000,000)² x² - y² = (150,000,000)² x²y² = (150,000,000)²

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
