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.
1 = 4
a2 = -2(a1) - 1
a2 = -2(4) - 1
a2 = -9
a3 = -2(a2) - 1
a3 = -2(9) - 1
a3 = -19
Can you do a4 and a5 and answer?
We have an inequation:
x/3 < 3
⇒ x < 3*3
⇒ x < 9
The final answer is x < 9~
