A glacier in Alaska moves about 29.9 meters a day. About how much farther will mobe in 1,000 days than it will move in 100 days
Reptile [31]

Answer:

26,910 meters

Step-by-step explanation:

The glacier moves 29.9 meters a day.

In 100 days it will move 29.9(100)=2990 meters.

In 1000 days it will move 29.9(1000)=29900 meters.

29,900-2,990=26,910 meters

Y=x+4 y=-2x-2 explain the awnser plz
Sliva [168]

Answer:

x = -2 and y = 2

Step-by-step explanation:

We have the following system of linear equations;

y=x+4

y=-2x-2

To solve the above system, we shall be equating the right hand sides of the two equations since we have y's on the left hand side of both equations;

x + 4 = -2x - 2

add 2x on both sides of the equation;

x + 4 + 2x = -2x - 2 + 2x

3x + 4 = -2

subtract 4 on both sides of the equation;

3x + 4 - 4 = -2 - 4

3x = -6

x = -2

We can use the first equation y=x+4 to determine the value of y;

y = -2 + 4

y = 2

The solution to the system of linear equations is thus;

x = -2 and y = 2
