Answer:
Step-by-step explanation:
The equation representing the growth of the plant after x weeks is expressed as
y = 0.2x+2
Where
x represents the number of weeks.
y represents the height of the plant after x weeks in inches.
A.
The height of the plant after week 3 was about 2.6 inches. We can check by substituting x = 3 into the equation. It becomes
y = 0.2 × 3 + 2 = 2 + 0.6 = 2.6 inches. It is correct.
B is incorrect.
C.
The height of the plant after week 9 was about 3.8 inches. We can check by substituting x = 9 into the equation. It becomes
y = 0.2 × 9 + 2 = 2 + 1.8 = 3.8 inches. It is correct.
D is incorrect
the answer is x3
11x3=33
5x3=15
multiply by 3 on all of them

Answer:
.9
Step-by-step explanation:
9 divided by 10
To write this equation, you need use the formula y=mx+b.
m represents the slope and b represents the y intercept.
The y intercept is the point where the line touches the y axis. In this case, the y-intercept is 1.
The slope is just rise over run from one coordinate to another. The slope is 2/-1 which could be simplified as -2. The slope just means that we are going up 2 and left 1 to get to a new coordinate.
The equation is y=-2x+1
