Answer:
1) For each value of x, a value of y is increased by 5.
x = 0, y = 5
x = 1, y = 10
x = 2, y = 15
x = 3, y = 20
------------------------------------------------------------------------------------------
2) For each two values of x, a value of y is increased by 10.
x = 0, y = -2
x = 2, y = 8
x = 4, y = 18
x = 6, y = 28
-------------------------------------------------------------------------------------------
3)
x = 0, y = 1
x = 1, y = 
x = 5, y = 3
x = 10, y = 5
-------------------------------------------------------------------------------------------------
4)
x = 0, y = 2
x = 1, y = 17
x = 2, y = 32
x = 5, y = 77
Step-by-step explanation:
This is as easy as replacing x for the actual value show on the table.

-------------------------------------------------------------------------------------------------
4)

When x = 0, y = ?

When x = 1, y = ?

When x = 2, y = ?

When x = 5, y = ?

Answer:
x=20
Step-by-step explanation:
just use the pythagorean theorem!!
square 12 and 16 to get 144 and 256
add those together to get 400, and then just take the square root of 400 (which is 20)
this means that x=20!
hope this helps!! :)
R/6<= 3
Multiply 6 on both sides
Final Answer: r<= 18
