My work is shown up above in the picture.

Answer : (-2,1)

My answer is definitely right. I checked my answers by using x and y into the two equations. In other words using the substitution method.

Answer:

(3, 1)

Step-by-step explanation:

Next time, please include the directions:  "Find the solution of the system of linear equations using linear combinations:

-4x-10y=-2

4x+ 3y= -5

----------------

      -7y = -7, so y = 1.  If y = 1, then -4x - 10y = -2 becomes

-4x - 10(1) = -2, or

-4x + 10 = -2, or

-4x = -12.  Then x must be +3.

The solution to this system of linear equations is (3, 1).

Answer:

1/10

Step-by-step explanation:

1 + 1/2 = 1 1/2

1 - 1/8 = 7/8

1 + 1/5 = 1 1/5

1 - 1/3 = 2/3

1 + 1/10 = 1 1/10

One and one tenth is closest to one because one tenth is the smallest amount that would need to be added or taken away to get exactly one. Hope I helped!

RSM was founded in 1996. From 1996 to 1997, the number of students in RSM doubled. From 1997 to 1998 the number of students doub
kaheart [24]
To find the increase from 1997 to 1998, you could substitute in numbers and then determine the percent increase based on those numbers.

Ex: 500 to 1000 (96-97)
      1000 to 2000 (97-98)
Percent increase is (2000-1000)/1000 or 100% increase.

Testing another set of numbers will result in the same thing.

Ex: 200 to 400 (96-97)
      400 to 800 (97-98)
Percent increase is (800-400)400 or 100% increase.

The percent increase is 100%.
