Answer:
Step-by-step explanation:
1. y = 1/4 x + 7
2. y = -3 x + 2/3
3. y = 2/3 x + 2/3
4. y = -2 x - 1/2
5. y = -3/4 x - 3
Answer:
Step-by-step explanation:
<u>Plant A growth over 2 weeks:</u>
<u>Average rate of change after 2 weeks or 14 days:</u>
<u>If you need it in inches, then convert as below:</u>
- 1.5 cm = 1.5 * 1/2.54 in = 1.5/2.54 in = 0.59 in per day (rounded0
Answer:
daylilies - $12; ivy - $7
Step-by-step explanation:
one way to answer this question is by using two equations
first write your let statements
let d be daylilies and let i be ivy
7d + i = 91
7d + 3i = 105
then you can subtract the equations
you get -2i = -14
then divide eveything by -2
i = 7
ivy costs $7
lastly plug this into an equation
7d + 7 = 91
7d = 84
d = 12
daylilies cost $12
