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>
</h3>
M = miles Marcos drove
c = miles Candice drove
m = 2c
m + c = 66
Plug m=2c into the second equation :
m + c = 66
(2c) + c = 66
3c = 66
Choice A
Divide 361 by 2
180.5
Divide 173 by 2
86.5
180.5+86.5=267
One of the # is 267
361-267=94
The other is 94
