Question

Mark recorded the growth of a plant over 8 weeks. The equation y=0.2 x+2

Answer 1

Answer:

A. The height of the plant after week 3 was about 2.6 inches.

C. The height of the plant after week 9 was about 3.8 inches.

Step-by-step explanation:

The equation given:

Y = 0.2x + 2

x represents the number of weeks

substituting x = 3 into the equation , we will have

y = 0.2(3) + 2

y = 0.6 + 2

y = 2.6

This means that  the height of the plant after week 3 was about 2.6 inches.

Also , substituting x = 9 into the equation will give

y = 0.2 (9) + 2

y = 1.8 + 2

y = 3.8

This means that the height of the plant after week 9 was about 3.8 inches.
