X>9 is how you would write X is greater than 9.
Let, J = John and B = Bob
2J = B
Because you didn't give me a number we are making an expression
2J = b
Make J = 1
J = b/2
Find out how many times 25 goes into 100, it goes in 4 times so you do 19×4
19×4=76
The ordered pairs would be (x-2, -y).
Translating a graph to the right subtracts the number of units from the x-coordinate.
Reflecting across the x-axis negates the y-coordinate.
