Answer:
B. y - 35 = 2(x - 10)
Step-by-step explanation:
The height of the plant, y, after x days could be modeled by the equation
<h3>y-y0=k(x-xo) (1)
,</h3><h3>
where y0 was the initial height at 'x0'th. day, and k is the constant of proportionality.</h3><h3>
From equation (1), k could be evaluated as follows:</h3><h3>
k=(y-y0)/(x-x0) </h3><h3>
From the problem statement, we may determine k by plugging in the given values, e.g. y0= 35, x0=10, y=55, x=20.</h3><h3>
Thus,</h3><h3>
k=(55-35)/(20-10)=2</h3><h3>
Therefore, the model equation becomes</h3><h3>
y-35=2(x-10)</h3><h3>

Answer:
The answer is 11/8 or 1 3/8
Step-by-step explanation:
First, you can break both fractions down into 3+1/4-1+7/8.
Second, use 3 subtract 1, you will get 2+1/4-7/8.
To subtract 7/8 you have to make both numbers denominator same.
1/4 will multiply by 2 on the top and the bottom.
After that, you will get 2 2/8-7/8.
2x8=16, 16+2=18
18/8-7/8=11/8 or 1 3/8
I know its gonna be confusing, but this is all I can do, sorry about that. :)
