1. Use the table to answer the question.
x | 25, 58, 98
y | ?
The expression x + 76 shows an additive rule that is represented by the table. What is the missing value? 174, 76, 101 or 134.
2. Which of the following points located on a graph represents the additive rule x+12? (12,12), (1,12), (3,15) or (2,10).
1. The missing value can be found by adding 76 to each value in the x column:
25 + 76 = 101
58 + 76 = 134
98 + 76 = 174
Therefore, the missing value is 174.
2. The additive rule x + 12 means that you add 12 to the x-coordinate. Looking at the options provided:
(12,12) has an x-coordinate of 12, so adding 12 would give 24.
(1,12) has an x-coordinate of 1, so adding 12 would give 13.
(3,15) has an x-coordinate of 3, so adding 12 would give 15.
(2,10) has an x-coordinate of 2, so adding 12 would give 14.
Only (3,15) matches the additive rule x + 12, so the correct answer is (3,15).
