Which value of m will create a system of parallel lines with no solution? y=mx-6 8x-4y=12
1 answer:
Answer: y = 2x - 6
Step-by-step explanation:
Let us turn the second given equation into slope-intercept form to match the first equation.
8x - 4y = 12
8x - 12 = 4y
4y = 8x - 12
y = 2x - 3
Now, parallel lines have the same slope. This is the <em>m</em> value.
y = <u>2</u>x - 3
\/
y = <u>m</u>x - 6
y = 2x - 6

Answer:
- 160 ft (out from the river)
- 320 ft (parallel to the river)
Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the dimension of perpendicular to the river will be half the remaining fence: (640-x)/2. The total area will be ...
A = x(640-x)/2
This is the equation of a parabola that opens downward. It has zeros at x=0 and x=640, so its axis of symmetry is x = (0+640)/2 = 320. That is, the peak of the area curve is found when x=320.
The dimensions of the garden with the largest area are 160 ft wide by 320 ft long, where the long side is the river side.
