Answer:
2x = y
Step-by-step explanation:
As you can see in the table, y = 2x, this is proven by the fact that if you divide any value in the y of the table by 2 you will get its corresponding x value, proving that 2x = y is the function that is used to represent this table's value.
Answer:
?=7
Step-by-step explanation:
Here is a cool trick that I believe only works with 9.
Add the numbers, 3+9+9+8+x= divisible by 9.
3+9+9+7+8 is 36 which is the only number divisible by 9.
First number: x = 19
Second number: Y = -5
x + 2y = 9
2x + y = 33
x/3>-1
Isolate the x. Multiply 3 to both sides
(x/3)3 > -1(3)
x > -1(3)
x > -3
x > -3 is your answer
hope this helps
