Answer:
Step-by-step explanation:
- 3x-2y =7
- x+2y= -3
- 4x=4
- x=4/4
- x=1
- 3x-2y=7
- 3(1)-2y=7
- 3-2y=7
- -2y=7-3
- -2y=4
- 2y=-4
- y=-4/2
- y= -2
- Verify solution
- x+2y= -3
- 1+2y= -3
- 2y=-3-1
- 2y= -4
- y= -4/2
- y= -2

is
real and
rational.
For it to be an integer, whole, or natural number, it would have to be a whole number. Since it can be written as a repeating decimal (.6666666...) it is not irrational either.
Answer:
10
Step-by-step explanation:
1x^3-2x^2-4x-6
x^3-2x^2-4x-6
(4)^3-2(4)^2-4(4)-6
64-2(16)-16-6
64-32-16-6
32-16-6
16-6
10
So when x=4, the output will be 10
