The missing value n equals 17.
Step-by-step explanation:
Step 1; First, we need to determine the equation relating the x to the y values in the table. y is the dependent value whereas x is an independent value i.e. the y value depends on the value of x.
Step 2; If we multiply the value of x with 2 and add the resulting answer with 1 we get the y value.
y = 2x + 1 is the equation that relates the values in the table.
Step 3; Now we substitute the values in the equation
For x = 5, y = 2(5) + 1 = 10 + 1 = 11,
For x = 6, y = 2(6) + 1 = 12 + 1 = 13,
For x = 8, y = 2(8) + 1 = 16 + 1 = 17,
For x = 10, y = 2(10) + 1 = 20 + 1 = 21,
So the value of y when x = 8 is 17.
