Answer:
<h2>y = 6x + 9</h2>Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept → (0, b).
Parallel lines have the same slope.
Therefore if <em>k</em>: y = 6x + 7 → m = 6, and <em>l</em>: y = mx +b,
then <em>l</em> is parallel to <em>k</em> if m = 6.
We have the equation: y = 6x + b.
The line <em>l</em> passes through (0, 9). Therefore b = 9.
Finally we have:
<em>y = 6x + 9</em>
<u>Answer</u>:
the length of chicken coop and the garden is of 40 feet.
<u>Explanation</u>:
Given that the garden is the length of the chicken coop, equal length
→ 3x + 12 = 6x – 16
→ 3x - 6x = -16 - 12
→ -3x = -28
→
→
→ x = 9.33 feet.
- The garden length = 3(
) + 12 → 40 feet
- the chick coop length should be same as the garden length.
