R+6≥11 ; {4,5,6,7}

answer choices: 4, 5, 6,7

For this case we have the following inequality:

To solve we have:

Subtracting 6 from both sides of the equation:

Thus, the solution is given by all values of r greater than or equal to 5.

The solution is given by all values of r greater than or equal to 5.

i dont know sorry

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
