m=-4
you are subtracting all the numbers by 4 therefore they are all changing by -4
Answer:
Two subsets that form set of real numbers
You can take positive numbers and negative numbers subset
One subset become (- infinity,0]
other subset (0, infinity)
The answer would be b-5+6
See the picture, please!!
Find the soluiton
2x+2y=16
3x-y=4
x+y=8
<u>3x-y=4+</u>
4x=12
x=3
3(3)-y=4
9-y=4
y=5
(3,5)
test them to see if get true statment
obviously the first equatons of 1,2,4 work
1 doesn't work
2, works
4. doesn't work
2 is the same as the first except both euations are just doubled
answer is 2
