2nd equation:
8 x-y=10  ⇒ y= 8 x-10
We will switch that in 1st equation:
8 x-10=x²+12 x+30, or:
x² + 4 x +40 = 0,   a=1,B=4, c=40
Discriminant : D= b² - 4 ac= 16 - 160 = -144  and because it is negative there are no real solutions.

A team of astronauts is preparing a mission to the moon. The pull of gravity on the moon is different than on Earth. On the moon
erik [133]

Answer:

(C)xa+ya>\frac{1}{6}xa+\frac{1}{6}ya

Step-by-step explanation:

For this mission, each astronaut will bring

  • x pounds of food; and
  • y pounds of gear.

Weight of Supplies of One Astronaut on the earth = (x+y) pounds

If the total number of astronauts going on the mission= a

  • Total Weight on the earth of the supplies of all the Astronaut =a (x+y) pounds

On the moon, things weigh \frac{1}{6} of what they weigh on Earth.

  • Total Weight of the supplies of all the Astronaut on the moon =\frac{1}{6}a (x+y) pounds

Therefore,the inequality which correctly compares the weight of the supplies on the moon to the weight of the supplies on Earth is:

a (x+y) pounds >\frac{1}{6}a (x+y) pounds\\xa+ya>\frac{1}{6}xa+\frac{1}{6}ya
