Olivia is growing roses and keeps track of how much fertilizer (in ounces) she adds to the soil and how many blooms each rose bush has. She finds a linear relationship that can be modeled by the equation y = 1.345x + 4. When will Olivia only have 4 blooms?

Question

Olivia is growing roses and keeps track of how much fertilizer (in ounces) she adds to the soil and how many blooms each rose bush has. She finds a linear relationship that can be modeled by the equation y = 1.345x + 4. When will Olivia only have 4 blooms?

B When she only adds 1 ounce of fertilizer.When she only adds 1 ounce of fertilizer.
C When she adds no fertilizer.When she adds no fertilizer.
D Every bush will only have 4 blooms.

Answer 1

B When she only adds 1 ounce of fertilizer.

Answer 2

To find out when Olivia will only have 4 blooms, we need to substitute 4 for "y" in the equation y = 1.345x + 4.

4 = 1.345x + 4

Subtracting 4 from both sides, we get:

0 = 1.345x

Dividing both sides by 1.345, we get:

x = 0

This means that Olivia will only have 4 blooms when she adds no fertilizer, making option C the correct answer.
