In the equation y = 2x + ?, we are given the specific values of x (r) and y. By substituting these values into the equation, we can solve for the missing number. In this case, when r = 3 and y = 11, we find that the missing number that goes in the box is 5.
In the given question, we are given the equation y = 2x + ? and we are asked to find the missing number that goes in the box.
To find the missing number, we are given the information that when r = 3, y = 11. In other words, we are given a specific value for x (r) and its corresponding value for y.
We can substitute the given values into the equation y = 2x + ? and solve for the missing number.
Substituting r = 3 and y = 11 into the equation, we get:
11 = 2(3) + ?
Simplifying the right side of the equation:
11 = 6 + ?
To find the missing number, we can subtract 6 from both sides of the equation:
11 - 6 = ?
5 = ?
Therefore, the missing number that goes in the box is 5.
