Answer:
4/5 chance
Step-by-step explanation:
There are 4 numbers that fit the rule, 1, 3, 4, 5, since all of them are either odd or greater than 3. There will be a 4/5 chance of picking one.
Answer:
-6 and 6
Step-by-step explanation:
Because one is a positive and one is negative, they cancel each other out equaling 0.
Answer:
The table will be:
x y=x+1
1 2
2 3
3 4
4 5
5 6
The graph is shown in figure attached.
Step-by-step explanation:
We need to create table and graph the expression: 
Table is made, such that we take value of x and find value of y
You can take any values of x from negative values to positive values. I am taking values of x: 1,2,3,4,5 and find value of y.
So our table will be:
x y=x+1
1 2
2 3
3 4
4 5
5 6
Now, we will plot these value on the graph. x values will be on x-axis and corresponding y-values will be on y-axis.
The graph is shown in figure attached.
The permimiter of a is 18 and the area is 9
Answer:
16 and -4
Step-by-step explanation:
Let the 2 numbers be x and y with x > y
x+y=12
x-y=20
Adding the 2 equations, term by term on both sides, will eliminate y leaving an equation in x that we can solve
(x+x)+(-y+y)=(12+20)
2x=32
x=16
16+y=12
y=-4
16+-4=12
12=12
16--4=20
20=20
