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:

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

A choice got cut off and it’s “-11x+6y=13”. Thank you! And this is a quiz and I have other questions on my account! I need fast

Marrrta [24]

–11x + 6y = –13

Solution:

The points on the line are (5, 7) and (–1, –4).

Here, $x_1=5, y_1=7, x_2=-1, y_2=-4$ \

Slope of the line:

$$m=\frac{y_2-y_1}{x_2-x_1}$

$$m=\frac{-4-7}{-1-5}$

$$m=\frac{-11}{-6}$

$$m=\frac{11}{6}$

Using point-slope formula,

$y-y_1=m(x-x_1)$

$$y-(-4)=\frac{11}{6} (x-(-1))$

$$y+4=\frac{11}{6} x+\frac{11}{6}$

Subtract 4 on both sides of the equation.

$$y=\frac{11}{6} x+\frac{11}{6}-4$

$$y=\frac{11}{6} x+\frac{11}{6}-\frac{24}{6}$

$$y=\frac{11}{6} x-\frac{13}{6}$

Multiply by 6 on both sides of the equation.

$6y=11x-13$

Subtract 11x from both sides of the equation.

–11x + 6y = –13

Hence option A is the correct answer.
